摘要： A method and system for stabilizing the output frequencies of a multimode laser of the type which operates in at least three optical cavity modes includes detecting the intermodulation product frequency, using a suitable photodetector. The optical cavity modes may be either purely longitudinal for a single transverse mode, or may include radiation from multiple transverse cavity excitations, also with possible longitudinal plurality. The detector output is monitored for the intermodulation product beat signal which is contained in the detector current at the differences of the primary difference frequencies of the optical modes. A signal derived from the frequency of the intermodulation product term is compared with a reference signal, and the resulting error signal is driven to zero by varying the optical length of the laser oscillator cavity in response to the error signal, thereby causing the operating modes of the laser to be stabilized. Possible means of adjusting optical cavity length include, but are not limited to, thermal expansion or contraction of the resonator support structure which is used to establish the relative spacing of the laser's end mirrors, by piezoelectric or magnetostrictive means according to which one or both cavity mirrors is moved to change physical cavity length, or other electro-optic means which may be employed to adjust optical cavity length by control of the refractive index or optical path length presented by an intracavity optical element.

摘要： A near-eye display includes an image generator that generates angularly related beams over a range of angles for forming a virtual image and a waveguide that propagates the angularly related beams over a limited range of angles. An input aperture of the waveguide includes a plurality of controllable components that are selectively operable as diffractive optics for injecting subsets of the angularly related beams into the waveguide. An output aperture of the waveguide includes a plurality of controllable components that selectively operable as diffractive optics for ejecting corresponding subsets of the angularly related beams out of the waveguide toward an eyebox. A controller synchronizes operation of the controllable components of the output aperture with the propagation of different subsets of angularly related beams along the waveguide for ejecting the subsets of angularly related beams out of the waveguide for presenting the virtual image within the eyebox.

摘要： A near-eye display projects virtual images from an image generator to an eyebox within which the virtual images can be seen by a viewer. A first optical path conveys image-bearing light from the image generator to a selectively reflective powered optic and a second optical path conveys the image-bearing light along a line of sight from the selectively reflective powered optic to the eyebox. First and second selectively reflective surfaces fold the first optical path with respect to the second optical path to locate the image generator out of the line of sight to the eyebox. The image generator is effectively inclined to the line of sight to the eyebox for reducing a thickness of the near-eye display. The selectively reflective powered optic is oriented normal to local overlapping portions of the first and second optical paths at the selectively reflective powered optic.

摘要： Processing packet information using an array of processing elements involves performing search-independent processing on packet information in parallel with a search of a first stage memory unit and then using the processed information and the result from the search of the first stage memory unit to generate search information for a search of a second stage memory unit. The search-independent processing of packet information in parallel with search operations can be repeated at each stage of the array. By performing search-independent processing of packet information in parallel with search operations instead of serially, latency that is contributed from the relatively slow search operations is reduced.
