VL53L01x TOF (time of flight) sensor casing with small field of view
Description
i've been working with the vl6081x, and the vl53l0x for a bit, and have found the vl53l0 sensor to be better when trying to narrow its output field of view. i think it is because it uses a laser, and it is sensitive enough to look further away by default. i have project goals that require resolution of sensor to be +/-0.5mm, and reasonable resolution for scanning an area. this part requires 2 metal screws, 2 grub 4mmx 6mm or 8mm screws and a ~15mm x 22mm polarizing filter. so far it seems angle is not important, just that the filter laid across sensor curved as in image which it will be by default from the spring fitting into into part i have also listed this casing here: https://hackaday.io/project/176862-vl53l0x-tof-sensor-improved-scan-resolution-box I am not the first person to try to narrow the filed of view but believe i have made it repeatable, and reliably doable and have the smallest angle field of view possible. included is a 3d printed part file that makes the field of view less than 2 degrees at 200mm or about 8mm high and 4mm wide at 200mm. for shorter distances i have had field of view narrowed to 1mm x 1mm and get reasonable measurements up to 100mm away, but it becomes harder not to have sensor crash this 3d casing is adjustable in x and y degree fields of view. grubs are self tap part seems to print best upside down with tree support in cura. the peal away of the support can cause a white residue over the front of the filter casing, but it will be covered up by polarizing filter.
