Claim 0:
1. A method of detecting pulsed radiation, comprising the steps of:
providing an array of sensor elements, the sensor elements being arranged in element lines;
receiving pulsed radiation;
irradiating at least a portion of the array of sensor elements with the pulsed radiation;
addressing the array of sensor elements using a rolling shutter operation;
reading the array of sensor elements to obtain a radiation image; and then
applying a pulse detection operation to the radiation image, thereby detecting the pulsed radiation;
wherein the step of addressing the array of sensor elements comprises:
calculating a predetermined integration period using an integration period function, the integration period function being a function of an anticipated pulse repetition interval of the pulsed radiation;
configuring the rolling shutter operation to address each of the element lines for the predetermined integration period; and then
addressing the element lines.
