Hello everyone

Is it possible to reprogram the DMD to modify the tilt angle of micromirrors? How?

Thank you

Hi Marco,

The angle of the mirrors is an intrinsic parameter of the DMD that is determined by the MEMS structure and cannot be changed.

What are you looking to accomplish?

I'd want to reflect the rays to another direction because i want to use two different detectors.

Marco,

As Paul indicated, the DLP4500 has to position. The on position directs light from the grating to the detector. The off position directs light to the side wall to the right of the DMD and opposite to the direction of light from the grating. This illustration explains this:
