Abstract

A synchronous gating technique was proposed for fluorescent photon collecting. The two- and multi-gate rapid lifetime determination (RLD) technique was applied to implement on-chip fluorescence lifetime extraction. Compared with all available iterative least square method (LSM) or maximum likelihood estimation (MLE) based general purpose FLIM analysis software, we offer a method for the direct calculation of lifetime based on the photon counts stored in on-chip memory and deliver faster analysis to enable real-time applications. Theoretical error analysis of the two-gate RLD technique was derived for comparison. The performance of the algorithms were tested on a single-exponential histogram obtained from a CMOS SPAD detector chip using a 468nm laser diode light source with optimized gate width. Moreover, a multi-exponential pipelined RLD FLIM technique was also proposed and tested on a four- exponential decay DNA sample containing a single adenine analogue 2-aminopurine.
