  • Electron Microscope
    286 words
    The electron microscope, instrument that produced the first magnified image showing 'three-dimensional' and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder, which contains the lenses, the specimen chamber, and the image-recording system. Two types of electron lenses are used, electrostatic and electromagnetic. T...
  • Two Beam Splitters
    1,152 words
    Abstract: The interferometer is the most accurate measuring device known to man. It was created by Albert A. Michelson. The operation of the interferometer described briefly is a light beam that is separated by a beam splitter. The two beams then travel equal distances at 90^0 of each other where they are reflected off two mirrors back through the beam splitter. They are then superimposed on to a screen. The screen will display an interference pattern of fringes. The interferometer is extremely ...
  • Gabor's Theory About Light Waves
    1,123 words
    Toss a pebble in a pond -see the ripples? Now drop two pebbles close together. Look at what happens when the two sets of waves combine -you get a new wave! When a crest and a trough meet, they cancel out and the water goes flat. When two crests meet, they produce one, bigger crest. When two troughs collide, they make a single, deeper trough. Believe it or not, you " ve just found a key to understanding how a hologram works. But what do waves in a pond have to do with those amazing three-dimensio...
  • Back Of The Finger Light Case
    570 words
    A finger light is a device used by many pilots in place of backlighting on critical avionics equipment under low ambient light conditions. There are numerous avionics in the cockpit of the HH-60 G Pavehawk helicopter that do not have any backlighting and therefore require an alternate source of light to illuminate the avionics at night. Outfitting the pilots with fingertip lighting is the most economical solution to this potentially dangerous problem. This essay describes the finger light and it...
  • Polarized Light From The Second Filter
    298 words
    Shades Dear Mom, This past week i endeavored on the delightful effect of polarized light. My class conducted experiments on polarization and things such as how to label, find, and see what kind of things it would do. We set up many tests such as sunglasses, mirrors, glass, and filters. If the light off many different things would go through our filters then it would intern be polarized light. Then we would record, except for Mr. Hughes, he is still learning to read and write. Love, Kyle Steps 1....
