20180266938, Sep 20, 2018

Filed:

Mar 15, 2018

Appl. No.:

15/922112

Inventors:

- San Carlos CA, US
Vincent Y. Chow - San Carlos CA, US

International Classification:

G01N 15/14
G06K 9/62

Abstract:

A method and system for particle detection and characterization including a current confining pixel and a light source. The pair of light detectors may comprise a first light detector and a second light detector electrically coupled to one another. Further, the first and the second light detectors may be situated in parallel and may have inverse polarities. Further, the particle detector method and system can comprise a boundary vernier-line having a width separating the first and the second light detectors. It may comprise a signal processor for processing an output waveform generated by a particle as it flows unobstructed on or near the detector surface; wherein the output waveform is bipolar and a polarity of the output waveform may flip when the particle crosses the boundary vernier-line; and wherein the signal processor may analyze the output waveform to ascertain at least one property of the particle. Methods of using the same are also disclosed.

International Classification:

H01L 27/146
H04N 5/351

Abstract:

A system and method for optical perception can include a current confining pixel (CCP) that includes a detector pair, the detector pair including a first detector and a second detector, coupled together in an inverse polarity configuration such that the current confining pixel defines a sense node and a reference node together forming a differential output across the pair of detectors. The system and method can include a plurality of CCPs arranged in a CCP array, coupled together in any suitable manner; receiving, at a current confining pixel (CCP), an input signal; generating a differential output signal based on the input signal; and, analyzing an output of a CCP.
