Paper Abstract

A technique for calibrating the flat-field response and geometric distortion of optical streak cameras using high-power lasers and electro-optic pulse shaping hardware was reported previouslyl. The laser hardware provides a temporally-flat light pulse that can be used to calibrate streak cameras operating with sweep durations of 3-10 ns. Although this technique is successful, the hardware involved is expensive and the process is complex. Based on the analysis of calibrations made at these fast sweep rates, we developed a new technique to measure the flat-field response of an optical streak camera using an array of visible light emitting diodes (LED) and a slow (~10 μs) sweep generator. We will discuss the new slow technique, and will present a comparison between calibration measurements made using the two techniques.
