The original, simple, and efficient speckle suppression method has been proposed for a laser picoprojector. The method uses a simple 1D DOE structure on a flexible film roll-up in a loop for speckle suppression. The structure of 1D DOE is based on binary pseudorandom sequences. It almost does not re...
