DLP for LIDAR

LIDAR can be effective in detecting objects, but the beam width is extremely narrow.  Some devices overcome this limitation by using rotating mirrors, but such implementations are heavy and expensive.

For applications that didn't need a large FOV (+/- 15 degrees, for example), would it be possible to use a DLP device to perform the scanning?

  • Charles,

    A digital micromirror device (DMD) has two operational states, typically at ±12° for most.  The transition between the two states is not controllable, so that it cannot be used to scan in angle space.  However with the proper optical system each pixel can map to an area of the field of view (FOV), so that controlling the pattern of on and off pixels can create a scan of the FOV.

    I hope this helps.

  • Given that limitation, I don't think it would work very well for LIDAR.
