摘要： An apparatus, comprising two or more scan modules, each scan module having two or more laser sources that generate two or more laser beams and a beam deflector that deflects the two or more laser beams. A fluorescent emissive sheet (FES) receives the two or more laser beams deflected by the beam deflectors of the two or more scan modules and emit light of a first wavelength that is of a longer wavelength than that of the two or more laser beams at a first portion of the FES that is struck by the two or more laser beams. The two or more scan modules are disposed on a same side of the FES. The FES includes a second portion of the FES that emit a second wavelength of light that is different from the first wavelength and that has a longer than the wavelength than the two or more laser beams when the second portion is struck by the two or more laser beams. Imaging optics form a virtual image from the light emitted from the first portion or second portion of the FES that is struck by the two or more laser beams.

摘要： An apparatus, comprising, a scan module having one or more laser sources that generate one or more initial laser beams and two or more beam deflectors that deflect the one or more initial laser beams. A beam optic is configured to substantially collimate the one or more initial laser beams to produce one or more collimated laser beams. One or more beam deflector controllers are configured to control an angle of beam deflection from each beam deflector. Relay optics between the two or more beam deflectors are configured to image each sequential beam deflector in an optical chain onto the subsequent beam deflector in such a manner that the beam deflecting from a last beam deflector in the optical chain contains a combination or superposition of all the beam deflections of the beam deflectors in the sequence, and maintains a beam divergence of the one or more collimated beams. A first beam deflector of the two or more beam deflectors is configured to scan about a single axis and a second beam deflector of the two or more beam deflectors is configured to scan in a quasi-static mode about two orthogonal axes.

摘要： A MEMS device includes a movable mirror and a solid material below the mirror that removes more heat from the mirror and creates more viscous drag than if the solid material were absent while allowing free movement of the mirror. A MEMS system includes a movable mirror, transparent window, electronic package, and a fluid-tight cavity between the window and the electronic package filled with a fluid exhibiting higher thermal conductivity than air. Another system has a reflective movable mirror, transparent window, and a lid that holds the window close to the mirror without obstructing its free movement. There is greater vertical clearance between the MEMS system and lid than between the mirror and MEMS system. Another MEMS device has a movable mirror and a surrounding substrate coplanar to the mirror. A gap between the mirror and substrate is filled with fluid. Finger structures extend from the mirror into the gap.
