[Laser] Optical communicator articles posted on the web

[Kerry Banke]

A couple of recent optical communicator articles I put together have been 
posted on the web at the following URLs. One is a general slide 
presentation in Power point of what we've been doing in our San Diego 
Microwave Group with lasers and the other is a specific article on the wide 
band laser link we just demonstrated this last weekend during Amateur Radio 
Field Day.  Our demo setup  in one direction was  video and audio from a 
video camera fed to a channel 3 RF modulator which was amplified to 0 dBm ( 
1 mw) and applied to the laser pointer. At the receive end we had a pin 
photo detector ( reverse biased for reduced capacitance) feeding the 
recovered channel 3  TV RF  to a television for audio/video display.  In 
the other direction we had a 2 meter FM handy talky attenuated on Tx to 0 
dBm and modulating the laser pointer directly. At the Rx end the same 
biased detector arrangement fed a 2 Meter HT set on receive.
