    摘要: Provided is a readout integrated circuit (ROIC). The ROIC includes a memory for each of a plurality of pixels, an address selector to synchronize a subsequent bias voltage for each of the pixels, a reference voltage recover switch to subtract the initial bias voltage from an output voltage of the integrated circuit and to result an integrator voltage for a sample and hold block, and a pulse-width control circuit to prevent crosstalk of the subsequent bias voltage between first and second ones of the pixels while a pixel clock selects adjacent columns. The memory maintains an initial bias voltage for each pixel during an initial integration frame time and during a sample and hold readout processing time. The sample and hold readout processing time is utilized to write a subsequent bias voltage for each pixel for a subsequent integration frame time to allow the first one of the pixels to have a different bias voltage than the second one of the pixels inside each integration frame time.

    摘要: A semiconductor detector has a tunable spectral response. These detectors may be used with processing techniques that permit the creation of “synthetic” sensors that have spectral responses that are beyond the spectral responses attainable by the underlying detectors. For example, the processing techniques may permit continuous and independent tuning of both the center wavelength and the spectral resolution of the synthesized spectral response. Other processing techniques can also generate responses that are matched to specific target signatures.

    摘要: A photodetector for use at wavelengths of 2 μm and longer has an intersubband absorption region to provide absorption at wavelengths beyond 2 μm, integrated with an avalanche multiplier region to provide low-noise gain. In one particular design, the intersubband absorption region is a quantum-confined absorption region (e.g., based on quantum wells and/or quantum dots).

    摘要: Exemplary embodiments provide an infrared (IR) retinal system and method for making and using the IR retinal system. The IR retinal system can include adaptive sensor elements, whose properties including, e.g., spectral response, signal-to-noise ratio, polarization, or amplitude can be tailored at pixel level by changing the applied bias voltage across the detector. “Color” imagery can be obtained from the IR retinal system by using a single focal plane array. The IR sensor elements can be spectrally, spatially and temporally adaptive using quantum-confined transitions in nanoscale quantum dots. The IR sensor elements can be used as building blocks of an infrared retina, similar to cones of human retina, and can be designed to work in the long-wave infrared portion of the electromagnetic spectrum ranging from about 8 μm to about 12 μm as well as the mid-wave portion ranging from about 3 μm to about 5 μm.
