Techniques, systems, architectures, and methods for amplifying the time difference between events detected on a focal plane array, allowing greater resolution than that afforded by a reference clock are herein disclosed.

In pixel time amplifier for LIDAR applications

Techniques, systems, architectures, and methods for reducing peak power during an Analog-to-Digital Conversion (ADC) process, in embodiments on a Focal Plane Array (FPA).

Low power in-pixel single slope analog to digital converter (ADC)

Devices and methods of minimizing the temporal error between pixels or groups of pixels on a focal plane array involving, on a focal plane array comprising at least two pixels or groups of pixels, at least one counter or ramp, and at least one trigger: determining the timing error associated with a time stamp associated with the at least two pixels or groups of pixels; storing the timing error associated with the at least two pixels or groups of pixels and the pixel or pixel group location; and using the stored timing error and pixel or pixel group location to correct subsequent time stamps associated with the at least two pixels or groups of pixels, wherein the timing error corresponds to a systematic error between the trigger and the counter or ramp value due to the location of a pixel or group of pixels on the focal plane array.

Sensor readout with timestamp calibration

A light sensing apparatus includes: an arrangement of light sensing pixels, one or more pixels each associated with a noise floor and able to detect a triggering level of incoming light above the noise floor from a corresponding portion of a scene; readout circuitry to process and reset the triggering pixels; and an automatic gain control (AGC) to raise the noise floor of one or more pixels. Sometimes, the light sensing apparatus is part of a seeker that includes control circuitry to dynamically control the AGC to raise the noise floor of one or more pixels by an adjustable amount that varies in relation to the distance between the seeker and an intended target. Sometimes, the control circuitry dynamically controls the AGC in response to a concurrent triggering of two or more triggering pixels. or in response to a gain schedule corresponding to guiding the seeker to the intended target.

Light sensing apparatus with automatic gain control

A system and method for improved detection of lasers for use in laser guidance systems. By providing background illumination via one or more radiation sources the accuracy of the laser detection system can be improved. A closed loop system detects the background current on the detector and provides additional illumination when the back ground level is below a threshold current value thus providing for a faster detector response.
