System and method utilizing a reconfigurable in real-time phase-modulating diffractive device (in a specific case&#x2014;a 2D array of micro-mirror elements) in conjunction with another diffractive element (active or passive) to spatially steer a beam of polychromatic light such that light reaches the identified target without being substantially angularly dispersed.

Diffraction-based light beam scanner

Optical switch based on a micro-minor device such as a DMD configured to simultaneously switch light from N inputs to M outputs with switching times of about 10 microseconds, where N and M are generally greater than one. The minors of the device are oriented according to a pattern calculated based on a Fourier Transform of spatial distribution of M outputs such as to form, in diffraction of light incident on the device, and diffraction light pattern that in the output plane is substantially congruent with the spatial distribution of M outputs. The device can be configured as a modulator of amplitude and/or a modulator of phase of incident light wavefront.

Reconfigurable diffractive optical switch and method for operating the same

Optical switch based on a micro-mirror device such as a DMD for simultaneous switching light from N inputs to M outputs with switching times of about 10 microseconds, where N and M are generally greater than one. The mirrors of the device are oriented according to a pattern calculated based on a Fourier Transform of spatial distribution of M outputs such as to form, in diffraction of light incident on the device, an diffraction light pattern that in the output plane is substantially congruent with the spatial distribution of M outputs. The device can be configured as a modulator of amplitude and/or a modulator of phase of incident light wavefront.
