US 11,635,496 B2 · Data reduction for optical detection

Abstract

In an optical detection system, features of interest can be identified from ADC circuitry data prior to inter-circuit communication with downstream object or target processing circuitry. In this manner, a volume of data being transferred to such downstream processing circuitry can be reduced as compared to other approaches, simplifying the receive signal processing chain and providing power savings. First-tier signal processing circuitry to identify features of interest can be located on or within a commonly-shared integrated circuit package with ADC circuitry, and downstream processing circuitry for object processing or range estimation can be fed with a data link meeting less stringent requirements than a link between the ADC circuitry and first-tier signal processing circuitry.

Dependent claims

An optical detection system, comprising:

an analog-to-digital conversion (ADC) block comprising at least one input channel, the ADC block configured to receive an electrical signal obtained from a corresponding photosensitive detector and configured to provide an output comprising a digital representation of the input determined by a conversion resolution and a conversion rate defined by the at least one input channel;
and
a signal processor circuit configured to receive the digital output from the ADC block and to identify at least one temporal window within the ADC output corresponding to a feature, the signal processor circuit comprising a digital output to provide an abbreviated representation of the digital output from the ADC block corresponding to the at least one temporal window including the feature, the digital output transmitting the abbreviated representation.
