Abstract
The cross-correlation function between two light fields is recorded with the help of a new device. The proposed correlator exhibits ultrashort time resolution. The optical path difference between the two interfering beams does not have to be known with interferometric precision. The experimental dynamic range proved to be as large as 105. The device features imaging capabilities that could be applied to the analysis of two-dimensional images with ultrashort time resolution.
