摘要: Techniques are disclosed to accurately measure the integration or accumulation of charge measured by photosite readout circuitry due to a photodiode generated current, which is generated by a photodiode as a result of impinging light reflected onto the photodiode that forms part of an imaging sensor. The techniques described herein address shortcomings of photosite operation by using a series of sequential switching states that function to maintain the charge accumulated during idle sampling times between active detection windows.

摘要: Depth sensors comprising a focal plane array with photosites (PSs) directed in different directions, each PS operable to detect light arriving from an instantaneous field of view (IFOV) of the PS, a readout-set of readout circuitries (ROCs), each ROC coupled to readout-group PSs by multiple switches and operable to output an electric signal indicative of an amount of light impinging on the readout-group PSs when the read-out group is connected to the respective ROC via at least one of the switches, a controller operable to change switching states of the switches, such that at different times different ROCs of the readout-set are coupled to the readout-group and are exposed to reflections from different distances, and a processor operable to obtain the electric signals from the readout-set indicative of detected levels of reflected light collected from the IFOVs of the readout-group and to determine depth information for an object.

摘要: Systems and methods for imaging in the short wave infrared (SWIR), photodetectors with low dark current and associated circuits for reducing dark currents and methods for generating image information based on data of a photodetector array. A SWIR imaging system may include a pulsed illumination source operative to emit radiation pulses in the SWIR band towards a target resulting in reflected radiation from the target; (b) an imaging receiver including a plurality of Ge PDs operative to detect the reflected SWIR radiation and a controller, operative to control activation of the receiver for an integration time during which the accumulated dark current noise does not exceed the time independent readout noise.

摘要: An integrator having an offset evaluation circuit and a collected charge reduction circuitry and method for using the integrator. The integrator includes an amplifier, operable to amplify an input signal, an integration capacitor for collecting charge indicative of a level of the input signal and an offset capacitor. The offset evaluation circuit is operable to charge the offset capacitor with charge corresponding to an offset voltage of the amplifier and the collected charge reduction circuitry is operable to collect charge resulting from disconnection of the offset evaluation circuit, thereby reducing an amount of charge and associated noise input to the amplifier.
