Abstract
Two-photon scanning microscopy has been successfully applied in studying tissue structures and biochemistry with subcellular spatial resolution. We developed a 16-channel two-photon scanning microscope with high-performance single photon counting readout electronics. The apparatus incorporates a mode-locked Ti:Sapphire laser, a scanning microscope, a spectrograph with multi-anode PMT (16 channels with ~ 7 to 10 nm spectral resolution each), and a 16-channel photon counting card (PhCC) with integrated high-speed data link (payload 1.2 Gbps). Each PhCC detection channel features single-photon sensitivity and 100 MHz photon counting bandwidth. The multi-color single-photon counting detection scheme allows ultra-sensitive measurements in a broad spectrum of biomedical applications. We present spectroscopic studies of ex vivo tissue autofluorescence.
