  • Patent number: 6188473
    Abstract: The invention relates to a method and a system for photodetection in which measurement signals during photon-counting operation and current operation can be tapped off in parallel at a photomultiplier through two channels, one of which is a photon-counting (pulse-counting) channel and the other an analog signal transfer channel. The signals are stored continuously and processed in a microprocessor. The two-channel operation allows the dynamic range of the photomultiplier to be expanded, in which, for each time interval, the measured value for the light to be measured is selected on the basis of an adjustable range limit from the channel that operates as a photon counter or the channel that is operated in the current mode.
