Abstract
A kilohertz scanning optical delay line is demonstrated by means of employing a prism array formed by identical wedge prisms. The wedge prisms are lined up with one another and uniformly disposed on a rotational wheel. The optical path length of a light beam can thus be scanned as the prisms pass through the beam periodically. Scanning rate of 2 kHz, scanning amplitude of 3.5 mm, linearity of 99%, and duty cycle of 95% can be achieved simultaneously. Simplicity and rigidity are embedded in the design. Preliminary test results are presented.
