Laser sensor with narrow FOV

Post by acro »

Hi

I need a very precise laser to measure where my fingers are when they are about 40 cm away from the sensor. I have been looking on VL53L1X but since I am going to have maybe 20-30 lined up next to eachother I need to have a very narrow field of view so that they dont collide with eachother. Are there any more narrow sensor then VL53L1X that I can use for this? That still is class 1? Im going to use this in a public space so that is important.

I attach a small sketch:

It might be easier to use a camera, with some image processing. Consider the narrow field of view version of the MLX90640 thermal sensor, as well. https://www.adafruit.com/product/4407

You might want to consider something like the Leap Motion Controller. It is designed specifically for tracking hand & finger motion: https://www.adafruit.com/product/2106
