Do infra red rays spread out or do they work the same as lasers and fire in a single ray?
Example if I have the emittor at different distances from the object it is scanning (e.g a ground surface say 10mm and 30mm distances) do the rays spread and further to cover a wider range, or do they fire down straight no matter the distance?
Thanks.
