As I try to create a tool for my job (wood worker), I try to create an unscalling with distance pattern from a laser DOE (1mW laser is enough, and I do have laser glasses for other tools).
An DOE (Diffractive Optical Element) pattern usually scale with distance as
Using a set of lenses (in the reverse order of a camera) I should be able to get
the lens is my image is definitely going to be more complicated.
My questions is:
As far as I could research using bad keywords, a "telecentric" lens should do, but why? Is there another way to achieve that? (with other objects than lasers)
