Hello James,

Thanks for your insight.

I have also thought about the need for faster acquisition of random 
laser comms.
One thought was the CCD camera with the video fed into a PC and to use 
video
processing software to determine regions of interest (ROI), for further 
processing.

Scan for the pixel or pixel cluster that is brightest, then process for 
the modulation.

If after processing evaluation, the pixel is not of interest, lock it 
out of any further scanning processing.

MATROX sells video input cards and special software development packages
for ROI determination/processing. The CCD video output could be any common
format like NTSC, PAL, SECAM etc. May be even much higher resolution, 
like suitable for HD.

With the much broader viewing angle, many possible laser comm emitters 
could be identified.
Or the initial pointing to a specific emitter could be easier, let the 
PC sort things out.

I talked with MATROX a few months ago about a sample issue of their 
video processing software
development package, but got no where.

I am not a programmer/coder, so this project fell to the wayside,  like 
many others.
