Hey there
In school i am working on a project where i need to measure a box. I am currently not sure how to do it but have come up with this ida.
To put a row of laser diodes pointing into a row of phototransistors, and then measure the lenght of the box determined on how many of the lasers that have been "cut of"
Though i have had some trouble finding some laser diodes with a low divergense, only down to 7.5 degree, (to be honest i don't even know if this is high or low).
Is this possible, and do you guys have any recomendations on what laserdiodes to use.
