Hi all, I'm implementing a computer vision system with a near-infrared laser and a NIR bandpass filter. It shines a laser on things and looks for a reflection. I'm getting a bunch of interference from sunlight and was thinking of using a polarizing filter to cut some of the sunlight out. Anyone know if laser light is polarized to begin with, and in which direction? Most of the sunlight interference isn't direct, but reflection off a concrete floor. Anyone have experience with this? Other ways to cut out sunlight from laser light other than polarization? I'm open to all suggestions! Thanks so much.
