What is DOE(Diffractive Optical Elements)
DOE(Diffractive optical elements) are emerging optical elements that have developed vigorously in recent years. DOE usually adopts the micro-nano etching process to form two-dimensional diffraction units. Each diffraction unit can have a specific morphology, refractive index, etc., so as to finely control the phase distribution of the laser wavefront. The laser light diffracts after...
