Abstract:

Briefly, in accordance with one or more embodiments, a scanning module for a scanner system comprises a frame having a first section and a second section. The first section of the frame is capable of receiving a laser to secure the laser in the first section, and the second section of the frame is capable of receiving a MEMS device having a mirror, to secure the MEMS device in the first section. The laser is aligned with the mirror by the frame to cause light emitted from the laser to impinge upon the mirror during operation of the laser. Such an arrangement may facilitate the physical and/or electrical assembly of the components of the scanner system.

US Classification:

361714, 353 52

Abstract:

A thermally dissipative housing () includes a rigid housing () and a compliant heat spreader (). The compliant heat spreader () is thermally coupled to a heat-generating component () disposed within the thermally dissipative housing (). The compliant heat spreader () removes heat from the heat-generating component () and transfers it along an interior surface of the rigid housing () by passing along an interior () of the rigid housing () across at least a portion of the interior surface area () of the rigid housing (). The compliant heat spreader () transfers heat to the surface of the rigid housing () without substantially interfering with the shock absorbing properties of the rigid housing ().

Abstract:

A beam combining device combines laser beams and performs speckle reduction of the laser light. Two laser beams are incident on a non-polarizing beam splitter and combined beams are split into two light paths with different optical path lengths. The two light paths may have different geometric path lengths and/or different indices of refraction in the paths to produce the different optical path lengths. One of the light paths is passed through a polarization rotation device and then the two light paths are recombined with a polarizing beam splitter to produce a combined reduced speckle laser beam.

Abstract:

The embodiments described herein provide scanning laser devices that include a relay optic between scanning surfaces. In general, the relay optic is configured to reimage the laser beam reflecting from a first scanner onto the second scanner. Specifically, the relay optic is configured to reimage a laser beam reflected from over an angular range from a first scanning surface of a first scanner onto the scanning surface of the second scanner. This can effectively make the exit pupil of the scanners substantially coincident, and thus can reduce the exit pupil disparity between the scanners that would otherwise exist.

Abstract:

Devices and methods are described herein that use a first solid figure element, a polarizing beam splitter, and a second solid figure element or array of mirrors to reduce speckle in projected images. Specifically, laser light is generated and split into two portions having orthogonal polarizations. The first portion of laser light is reflected in the second solid figure element or the array of mirrors and is then spatially recombined with the second portion of laser light in the first solid figure element. The difference in path length followed by the two portions generates a temporal incoherence in the recombined laser light beam, and that temporal incoherence reduces speckle in the projected image.

Abstract:

Devices and methods are described herein that use a first solid figure element, a polarizing beam splitter, and a second solid figure element to reduce speckle in projected images. Specifically, laser light is generated and split into two portions having orthogonal polarizations. The first portion of laser light is internally reflected off at least three internal faces of the second solid figure element and is then spatially recombined with the second portion of laser light in the first solid figure element. The difference in path length followed by the two portions generates a temporal incoherence in the recombined laser light beam, and that temporal incoherence reduces speckle in the projected image.
