摘要： One embodiment relates to a laser positioning device for sensing relative movement between a data input device and a surface by determining displacement of image features in a succession of images of the surface. The device forms a single integrated package, which includes a planar substrate and a transparent encapsulant that also embodies a collimating lens. Both a coherent light source and a sensor array and associated circuitry are configured on the planar substrate. Another embodiment relates to a method of sensing relative movement between a data input device and a surface. Coherent light is emitted from a laser and collimated so as to form a collimated illumination beam with a predetermined diameter, D, and a substantially uniform phase front. A speckle pattern is generated by impingement of the collimated illumination beam on the surface and detected by a sensor array. Other embodiments are also disclosed.

摘要： An apparatus for selective blocking WDM channels comprises a light modulator, a diffraction grating, and a transform lens. The light modulator comprises an array of pixels. Each pixel of the light modulator is selectively operable to direct light into a first mode and a second mode. The first mode directs the light to an output. The second mode directs the light away from the output. The diffraction grating is operable to receive the WDM channels from an input and to disperse the WDM channels into a range of angles. The transform lens couples the diffraction grating to the light modulator. The diffraction grating is operable to transform the range of angles of the WDM channels into a range of spatially distinct positions along the array of pixels of the light modulator without overlap of two of the WDM channels on an individual pixel. In operation, the light modulator directs at least one of the WDM channels into the second mode while directing a remainder of the WDM channels into the first mode. The light modulator is capable of operating with a large dynamic range, thereby enabling equalization of select, transmitted WDM channels as well as blocking any arbitrary channels over the spectral range of operation.

摘要： A holographic data storage (HDS) system and method are provided. Generally, the system includes: a light source for generating a coherent light; beam-forming optics for forming the light into collimated object and reference beams; holographic storage medium; a spatial light modulator (SLM) located in a path of the object beam from the beam-forming optics to the storage medium, the SLM having a number of pixels for encoding data to be stored in the medium into the object beam. Preferably, the SLM can modulate both the amplitude and phase of light from every pixel on the SLM. More preferably, the SLM is also located in a path of the reference beam to the storage medium to modulate the phase of the light to store multiple holographic pages of data in the same physical volume of medium through phase multiplexing. Other embodiments are also described.

摘要： In one embodiment, an optical navigation sensor for a computer mouse is designed to be operable on an optically transparent material. The optically transparent material may include a contact surface on which the mouse sits during normal operation. An optically rough tracking surface is provided below the contact surface. The mouse includes a light source that illuminates an area on the contact surface and an area on the tracking surface. The mouse may include a tracking sensor onto which the illuminated area on the tracking surface is imaged to detect mouse displacement. The mouse may also include a lift sensor that picks up specular light reflected from the illuminated area on the contact surface to generate lift information indicative of whether the mouse has been lifted off the contact surface. Tracking of the mouse displacement may be qualified with the lift information.
