We want to using some kind of SLM(spatial light modulator) to generate an uniform optical intensity distribution (in a small solid state angle, about 0.2 rad).I am not sure that can be realized by one beam incident on the DMD and control the reflect angle of each micro-mirror. The area of the expected intensity distribution are not so large (1 or several mm square or should be enough for our application. We using some laser light near 1060nm (average power is about 2 watts).
Hopefully, you have some experience share with us about our application. We hope to make the reflective light can be incident on the facet of one multi-mode fibre with equal intensity in the each small direction or small solid angles, this is our motivation.
