As is well known, the Crab pulsar displays a light curve with a characteristic double peak profile having a period of 33 milliseconds, almost aligned in phase over the whole electromagnetic spectrum. Since it is the brightest pulsar in the optical band (V 16), its pulse profile has been extensively monitored by several authors; it is also used as a standard candle to calibrate fluxes and for testing instruments with high time resolution. We have studied the optical light curve of the Crab pulsar by means of a novel photon counting instrument (dubbed AquEYE, the Asiago Quantum EYE), that has the capability to provide data with exceptionally high temporal resolution and time tagging accuracy of each incoming photon.

Abstract
As is well known, the Crab pulsar displays a light curve with a characteristic double peak profile having a period of 33 milliseconds, almost aligned in phase over the whole electromagnetic spectrum. Since it is the brightest pulsar in the optical band (V 16), its pulse profile has been extensively monitored by several authors; it is also used as a standard candle to calibrate fluxes and for testing instruments with high time resolution. We have studied the optical light curve of the Crab pulsar by means of a novel photon counting instrument (dubbed AquEYE, the Asiago Quantum EYE), that has the capability to provide data with exceptionally high temporal resolution and time tagging accuracy of each incoming photon.
