Patent ID: 8582098

Claim:
A single photon sensor comprising: At least one multichannel photosensor including a linear photo multiplying tube array selected from the group consisting of linear photo multiplying tube arrays having more than 4 photosensor channels, more than 8 photosensor channels, more than 16 photosensor channels and more than 32 photosensor channels, each photosensor channel having photosensitive pixels adapted to receive distinct light spectra from a light spectra separator to which optical fibers communicate polychromatic light, and producing current pulses in response to single photons of said received light spectra; A multichannel amplifier, each amplifier channel adapted to receive said current pulses corresponding to light spectra from a corresponding one of said sensor channels of said multichannel photosensor and to amplify said current pulses; and A multichannel photon counter, each counter channel adapted to receive said amplified current pulses from a corresponding one of said amplifier channels of said multichannel amplifier, said multichannel photon counter having an integrator adapted to sum said amplified current pulses in each counter channel over a predetermined time interval.
