[Laser] Success using Jason program for sending data via fluorescent or High Pressure Sodiu...

[Kerry Banke]

Last night I took  the suggestion from Yves to try the Jason software 
for communicating via  flourescent and HPS lamps.  I found Jason very 
easy to setup and use. I moved the center frequencies to 140 Hz.  In 
fast speed  the Rx  frequency span is too large and include  120 Hz 
so that was not useable. In Normal speed the total span is about 4 Hz 
which rejected the local 120 Hz light modulation nicely. The Tx 
signals from one laptop  fell nicely into the Rx receive window on 
the other and decoding took place automatically without any 
intervention or sound card frequency calibration.  Jason  looks like 
a good program for experimenting with this type  of optical  transmission.
