WebMay 6, 2024 · laser light is still light, any optical detector will work. If you want to only detect the laser light in the presence of ambient light, that's harder - you need. a narrow-band optical filter (expensive) to remove most of the ambient light. For a fixed-direction beam you can use a directional sensor (photo diode behind a small hole perhaps) to. WebApr 6, 2024 · You can build an electrical filter that will filter all other frequencies (interferences) except 50kHz much more easily than you can filter light. the unidirectional light of a laser is helpful too - as said above, make sure you use a 1-meter tube to exclude as much ambient (non-columnated) light.
