PIXEL CIRCUIT AND METHOD FOR OPTICAL SENSING

摘要

A pixel circuit that includes: a substrate body having a channel influenced by an electric field; an aperture in communication with the channel for receiving a fluorescent light input and moving electrons through the substrate body; and a plurality of sampling devices adapted to be switched on simultaneously to sample the moving electrons.

1. A method of optical imaging using a pixel circuit for use in fluorescence lifetime imaging, comprising the steps of:
receiving at a pixel circuit a fluorescent light input emitted from a material; receiving electrical outputs from the pixel circuit in response to the light input; performing a center-of-mass method (CMM) calculation using the electrical outputs; and determining a lifetime parameter (τ) based on the CMM calculation.
