    摘要: An assembly comprising a radiation source to generate a beam of radiation, a modulator for modulating the power of the beam of radiation as a function of the position of the beam within a field-of-view to maintain the beam's power within a desired exposure level as the beam scans the field-of-view, and a reflector oscillating in a sinusoidal manner to direct the beam of radiation onto a field-of-view.

    摘要: A general absolute value circuit for developing a true, symmetric or bipolar, absolute value output signal from an input charge signal, compact enough to be used on a sensor chip incorporated into (or used in combination with) a pixel processor of the type used in imaging and other systems that collect electromagnetic radiation as part of on-chip circuitry, includes a balanced differential amplifier combined with a merged dual shelf transistor structure. The balanced differential amplifier, in response to an input charge signal, drives the merged dual shelf transistor structure which in turn generates the desired true absolute value output signal. Such circuitry may be used in imaging systems to implement focal-plane processing algorithms or may be used for performing a single read true absolute value computation by a pixel processor located on a sensor chip. The merged dual shelf transistor structure enhances performance and speed of the processor in which it is incorporated.
