Abstract

We have designed and developed a 80 ps scanning optical delay line by using a novel helicoid-shaped reflective mirror. By using the mirror, a quasi-real-time scanning autocorrelator was demonstrated to measure a 1.7 ps optical pulse by spinning the helicoid mirror. The time delay was linear proportional to the spinning angle of the mirror. The resolution and the maximum scanning range were limited by the beam spot-size and the pitch distance.
