Abstract

We report the design and operation of a novel real-time optical pulse correlator, a device used for the measurement and correlation of ultrashort optical pulses. In our design, an accelerometer and a pair of integrators are used to obtain the instantaneous position of the rapidly moving arm of the correlator; this permits the attainment of a distortion-free display of the correlation trace even in the presence of significant nonlinearities in the motion of the oscillating arm.
