Photonics 2030 — Introduction to Biophotonics

Filed under: Education, Science, Technology — Tags: , , , , , , , — mikewb1971 @ 4:38 PM (16:38)

Biophotonics is the science of generating and harnessing light (photons) to image, detect, and manipulate biological materials. Biophotonics is an emerging area that uses light to define and understand the inner workings of cells and tissues. This course presents an overview of the above.

Course Modules

  • Biology review including DNA, proteins, cells, tissues and structures
        Lab 1: DNA Extraction
        Lab 2: Enzyme action
  • Light basics including electromagnetic spectrum lasers, their safety and operation, health physics
        Lab 3: Refraction, Total Internal Reflection and Power Measurements Lab
  • Geometric Optics
  •     Lab 4: Microscope Principles

  • Sensor Fundamentals — CCD Basics
  • Light Tissue Interaction including reflection, refraction, absorption and scattering
        Lab 5: Pulse-Oximeter, Temperature Sensor, Fat Analyzer

Student Competencies

Upon successful completion of this course the student should be able to:

  1. Explain the structure of DNA and its function.
  2. Explain the structure of a cell, its components and functions.
  3. Operate a low-power laser safely.
  4. Explain the difference between laser light and ordinary light.
  5. Describe the rectilinear propagation of light including microscope principles.
  6. Explain how light interacts with living tissues via reflection, refraction, absorption and scattering.

NOTES

Course components

  1. Theory
  2. Laboratory (Student must take and achieve 100% on a laser safety exam before entering the laser laboratories.)
  3. Internet Research

Photonics 2005 — Introduction to Laser Systems

Filed under: Education, Science, Technology — Tags: , , , , — mikewb1971 @ 4:02 PM (16:02)

Introduces the theory and operation of solid-state and gas lasers and presents continues wave and pulse systems. The course covers the laser power and energy measurements, characteristics of flash lamps, discharge circuits, and pulse forming networks for optically pumped solid lasers, SW arc lamps.  It also covers power supplies for CW-pumped lasers, safe operations and measurements with argon, CO2 and Nd: YAG.

Course Modules

  • Topical outline as laser characteristics
  • Helium-neon (He:Ne) laser
  • Argon-ion laser
  • Solid state characteristics
  • Neodymium-doped yttrium aluminium garnet (Nd:YAG) laser
  • Continuous-wave (CW) and pulsed beam diagnostics

Student Competencies

Upon successful completion of this course the student should be able to:

  1. Assemble, align and make operational a continuous-wave (CW) helium-neon (He:Ne) laser from parts.
  2. Align and make operational both an argon-ion and a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser.
  3. Discuss operational characteristics of gas and solid state lasers.
  4. Perform beam diagnostics on available lasers.

NOTES

Evaluations and Final Grade

Students are given three projects (three non-operational lasers).

  1. The first laser the student makes operational is a “C” for the course.
  2. If the student makes two lasers operational (non-order specific), the student receives a “B” for the course.
  3. A student will receive an “A” for the course if all three lasers are made operational.

Photonics 2001 — Optics

Filed under: Education, Science, Technology — Tags: , , , , — mikewb1971 @ 3:42 AM (03:42)

Presents basic geometrical (ray) and physical (wave) optics. The course covers the basics of the light reflection and refraction and the use of simple optical elements. It reviews light wave interference, diffraction, and polarization; the use of thin film coatings on mirrors; laser beam divergence in the near and far field; and the operation of such devices as gratings and quarter-wave plates. It also covers wavelength, dispersion, and refractive index measurements and the concept of modulation transfer function.

Course Modules

  • Reflection
  • Refraction
  • Optical Systems
  • Imaging with Single Lenses
  • Imaging with Multiple Lenses
  • Imaging with F-Stops
  • Imaging with Apertures
  • Imaging with Telescopes
  • Imaging with Microscopes
  • Collimators
  • Interference
  • Diffraction
  • Polarization
  • Aberrations

Student Competencies

Upon successful completion of this course the student should be able to:

  1. Explain how light propagates through an optical component from the standpoint of geometric and wave optics.
  2. Correctly handle and clean optical components.
  3. Perform exact laboratory experiments and keep an accurate notebook of the experiment.

NOTES

  1. This course is listed as “Photonics 2097-103 Independent Study” on my transcript, due to the class not having more than 12 twelve students signed up at the start of classes in August, 2008.

BTP vs. “Modern Whigs” ?

Filed under: Politics — Tags: , , , — mikewb1971 @ 12:04 AM (00:04)

Current mood: amused, intimidated (not really)

It seems that the Boston Tea Party has drawn the attention and ire of the Virgnia state affiliate of the “Modern Whig Party.”

Oh, wow, I am so . . . terrified. No, not really. I mean, come on, don’t these clowns have anything better to do with their time than attempt to whale away on another “third” party? Maybe someday they’ll get a clue and realize that all they’re doing is giving the BTP some no-cost publicity.

About the “Modern Whigs” — they’re a bunch of disaffected Republicans and Democrats attempting to unseat the Reps and Dems from their positions of power . . .  using planks cherry-picked from the Democrat and Republican platforms, mish-moshed together.

From the MWP’s national site —

The Modern Whig Party relies on common sense. The organization is the fastest-growing advocate for such issues as fiscal responsibility, strong national defense and bold social progression. We see the value of independent thinking and the danger of being limited to one distinct ideology. Since 1833, we have carried the mantle of America’s middle-of-the-road party.

That’s their distinction from the Democrats and Republicans?! The idea that they’re the “middle-of-the-road” group? What’s so special about that? Anyone can be “middle-of-the-road,” just that being so tends to get you run over by oncoming traffic from either side of that road. I suspect that being “middle-of-the-road” isn’t going to win them any elections, considering the way that the Democrats and Republicans have divided up the nation into competing fiefdoms and jealously guard their holds on the reins of power over everyone else.

I note that some in the BTP are worried about this hostile attention from the Virginia Whigs.

What sparked the ire of the Virginia Whigs was a comment by BTP refounder Jim Davidson in his BTP blog posting “In case they kill me for it”

Members of the Modern Whig party are apparently upset with me for my comments on this thread:

http://www.independentpoliticalreport.com/2008/12/update-from-the-modern-whig-party/

In particular these statements:

I find it difficult to care about unit designations and battle ribbons. My proposal would be to stop sending American troops to other countries to massacre their children and rape their women. Then there would be less need for these unit designations and campaign ribbons.

The Virginia Whigs also took exception to the next paragraph in Jim’s posting —

For their next trick, the Modern Whigs will demand campaign ribbons for DEA agents and other para military agency troopers involved in overseas suppression of trade and commerce in drugs.

by saying that “Davidson went on to malign individual DEA agents as paramilitary troopers.”

What’s wrong with that? I’ll go a step further and lump them in with the F-Troop, in that their very presence in American society should be considered an occupation of America like that of the German Schutzstaffel or the Russian Komitjet Gosudarstvjennoj Bjezopasnosti across Europe. The only real difference between the SS, KGB and the DEA and F-Troop isn’t one of operating philosophy or committment to doing the right thing on the parts of DEA and F-Troop, but of severity.

And if that wasn’t funny enough, apparently the Virginia Whigs have been told to “tone it down” by their party’s national executives. Ha ha ha — that’s a good one there — members of “America’s ‘middle of the road’ party” are getting too rambunctious for the tastes of their national executives!
