Claim Text:
1. An optical system configured to receive photons, the optical system comprising a photocathode configured to receive the photons, an anode and a plurality of dynodes, between the photocathode and the anode, in which each of the plurality of dynodes is configured to amplify an electron signal representative of the photons received by the photocathode, in which each of the plurality of dynodes is electrically coupled to a respective electrometer to provide a plurality of dynode-electrometer pairs; and a first processor electrically coupled to each respective electrometer, in which the first processor is configured to measure an output signal from each dynode of the plurality of dynode-electrometer pairs and to terminate signal amplification at a saturated dynode of the plurality of dynode-electrometer pairs.
