Unformatted text preview: = U O (d) U P = U O * 3. A hologram is created of thin object located 2 cm from the film plate. The hologram is then placed in a lens system 10 cm from a f=10 cm lens. When the hologram is illuminated what type image will be created by the lens and where will it be located? 4 (a) Using energy equations what is the surface temperature versus time for a 100 watt argon laser with a 0.5 mm 1/e 2 laser spot, at the center of the spot when hitting a silicon surface for a pulse of duration 10-5 sec. Give the diffusion depth at the end of the pulse. (b) Repeat (a) but with the material surface being aluminium. (c) Add to the plots the temperature vs time curve for half and one diffusion depth....
