摘要： A readout circuit is disclosed for use in an AM chirp LADAR system. The circuit comprises a photodetector such as a metal-semiconductor-metal detector coupled to a passive electronic filter. The filter output coupled to a capacitive-coupled transimpedance amplifier with an output coupled to an analog storage register. The analog storage register output is coupled to a sample-and-hold circuit which in turn is coupled to a sample and hold circuit. The output of the sample and hold circuit is digitized by an analog-to-digital converter circuit for further processing. The circuit may be used as a cell for the readout of an individual pixel on a photodetector or a plurality of cells used in a stack of integrated circuit chips for the read out of a plurality of pixels in a photodetector array.Each IC layer in the stacked photodetector imaging module of the invention is identical to its mates and has a unit cell comprised of a capacitance coupled transimpedance amplifier and analog storage register for receiving the output of a pixel in a detector array. The IC layers share one or more common busses on the module surface opposite the detector array. The common bus carries common signals such as power, clocks, and control signals. In the stacked configuration, each IC operates independently and outputs its signals on a unique output line. The stacked ICs operate under the same set of control vectors as the individual ICs comprising the stack. No communication is required between layers, simplifying the design and control process.

摘要： A LIDAR system that can accommodate both a clear atmosphere and be adaptable to environments in which smoke, dust or other particulates (i.e., a degraded environment) exist in the atmosphere around the target is described. The system operates in two fields of regard: clear view mode (wide field of regard) and a degraded view mode (narrow field of regard). The wide field of regard allows the output laser energy to be concentrated over a large number of detector pixels and thus resulting in high scene scan rate. The narrow field of regard allows concentrating the laser output energy on fewer pixels to compensate for the loss of laser energy due to atmospheric degradation. The combination of the ROIC and LIDAR modes of operation result in a system that is capable of operation under clear and degraded environments.

摘要： A method for using a depletion region in a solid state spectrometer unit cell or plurality of cells for sensing different wavelengths of electromagnetic radiation at different depths within the substrate of the device. Variable bias voltages on one or more p-n junctions in the device are used so that the depth of the depletion regions are selectively varied. By varying the depletion region thickness of the p-n junctions in the device, the wavelengths absorbed by the semiconductor device and resultant electron-hole pairs collected by the p-n junctions are varied. In one embodiment, the outputs of each of two unit cell p-n junctions are sensed and the difference calculated and output to suitable circuitry for display as representative of a particular range or frequency of the electromagnetic spectrum.

摘要： A 3-D LADAR imaging system incorporating stacked microelectronic layers is provided. A light source such as a laser is imaged upon a target through beam shaping optics. Photons reflected from the target are collected and imaged upon a detector array though collection optics. The detector array signals are fed into a multilayer processing module wherein each layer includes detector signal processing circuitry. The detector array signals are amplified, compared to a user-defined threshold, digitized and fed into a high speed FIFO shift register range bin. Dependant on the value of the digit contained in the bins in the register, and the digit's bin location, the time of a photon reflection from a target surface can be determined. A T0 trigger signal defines the reflection time represented at each bin location by resetting appropriate circuitry to begin processing.A reference insert circuit inserts data into the FIFO registers at a preselected location to provide a reference point at which all FIFO shift register data may be aligned to accommodate for timing differences between layers and channels. The bin data representing the photon reflections from the various target surfaces are read out of the FIFO and processed using appropriate circuitry such as a field programmable gate array to create a synchronized 3-D point cloud for creating a 3-D target image.
