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.
摘要翻译：用于选择性阻挡WDM信道的装置包括光调制器，衍射光栅和变换透镜。光调制器包括像素阵列。光调制器的每个像素可选择性地操作以将光引导到第一模式和第二模式。第一个模式将光引导到输出。第二种模式将光线远离输出。衍射光栅可操作以从输入接收WDM通道并将WDM通道分散到一定范围的角度。变换透镜将衍射光栅耦合到光调制器。衍射光栅可用于将WDM通道的角度范围变换成沿着光调制器的像素阵列的空间不同的位置的范围，而不需要在单个像素上的两个WDM通道的重叠。在操作中，光调制器将WDM信道中的至少一个引导到第二模式，同时将其余的WDM信道引导到第一模式。光调制器能够在较大的动态范围内工作，从而实现选择发送的WDM信道的均衡，以及在光谱范围内阻塞任何任意信道。
