Hi all.
I am designing a photodetector array for a high speed data acquisition system. In order to test the device I used commercially available red and green laser pointers, and I found out to my surprise that the laser light was switching on and off at ~150kHz (red) and ~450kHz (green). I thought that such a switching at a high frequency could help saving power, but I am quite skeptical.
Is this kind of switching common with laser pointers? Or should I go back and check my sensor for problems?
Thanks in advance.
