A comparison of flat-field measurement techniques for optical streak cameras

Conference ·
OSTI ID:6761558
A technique for calibrating the flat-field response and geometric distortion of optical steak cameras using high-power lasers and electro-optic pulse shaping hardware was reported previously. 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 (/approximately/10..mu..s) sweep generator. We will discuss the new slow technique, and will present a comparison between calibration measurements made using the two techniques. 6 refs., 5 figs.
