N2 - This paper describes the design of an active CMOS sensor array for fluorescence applications which enables time-gated, time-resolved fluorescence spectroscopy. The 64 × 64 array is sensitive to photon densities as low as 8 × 106 photons/cm2 with 64-point averaging and, through a differential pixel design, has a measured impulse response of better than 800 ps. Applications include both active microarrays and high-frame-rate imagers for fluorescence lifetime imaging microscopy.
