(2) Signal to noise ratio is degraded due to the gamma of the phosphor’s response. Averaging or summing of up to 256 frames improves dynamic range by up to 16x = +24 dB. (3) In normal (non-shuttered) camera operation, the frame rate is the fastest rate at which the laser may pulse and the camera can still separate one pulse from the next. With electronic shutter operation, higher rate laser pulses can be split out by matching the laser repetition to the shutter speed. (4) This is the damage threshold of the filter glass of the filters. Assuming all filters mounted with ND1 (red housing) filter in the front. Distortion of the beam may occur with average power densities as low as 5W/cm2. For latest updates please visit our website: www.o
