Abstract

Single photon sensitive cameras are extensively used in modern optics. Intensified cameras provide high spatial resolution and sub-nanosecond gating possibility, but suffer from low duty cycle and high acquisition times when used for observation of random processes. We propose and experimentally demonstrate a setup in which the number of photons detected within each frame can be controlled. We achieve this by gating the image intensifier adaptively depending on the number of detected events. The use of our system can increase the data acquisition rate and therefore enable photon counting experiments which were not feasible using standard intensified cameras.
