Don’t say anything proprietary. But let me see if I understand:
You want to take an optical signal (ms range, pulse train, wavelength xyz nm) and repeat it (amplify gain of 1) .
First, you don’t need a Cyprus PSoc for this. You are not processing anything. This can be built with components.
There are still some questions that the designer will ask you:
Sensed light wavelength spectrum: broadband, multiple or single; intensity/power?
Transmitted light wavelength spectrum: broadband multi, single.; intensity/power?
Frequency and signal shape? square wave. i.e. is it on/ off or does the signal vary.
Do you want other people to see it or should it be piped somewhere?
Is the light focused?
Here are a couple of approaches:
You need a detector circuit: Could be an Optoisolator or even a cheap CDS cell:
You can then send via wire to another location and regenerate using Cree LEDs.
Or you can have a master/slave setup like on electronic flashes.
Or IR headphone amplifiers. They operate in the audio range sensing and retransmitting IR..
Or use three cheap detectors with RGB filters. Then you can regenerate with three LEDs.
Lots of questions but this should get you at least thinking about what to tell the designer.
Good luck with your project.
