摘要
Clipped speckle patterns before and after an object displacement are detected by an Optic RAM detector. The real-time optical correlation between the detected patterns is realized based on a joint transform correlator by using liquid crystal television displays. To demonstrate the usefulness of the method, the vector velocity measurement of a light scattering object is proposed. © 1990.
