Abstract:
A method is disclosed for calibrating an optical measuring system (14, 18, 0, 22) of the type which reproducibly projects a beam of light (16) over an extended period of time. The deviation between an incident beam and a rerflected beam is measured on both sides (30, 32) of a parallel-sided calibration mirror (28).

Abstract:
Apparatus for measuring velocity is disclosed. The apparatus in its prefed embodiment comprises a first lens and a first array of photodiodes and a second lens and a second array of photodiodes. The photodiode arrays are functionally equivalent to low resolution vidcon camera tubes and momentarily store the image. As an object passes beneath the first lens, its image is stored on the photodiode array. The object then passes beneath the second array and the image is stored on the second array. After the image is stored on the second array a correlation is made between the two images by making an element by element comparison of the serial outputs of the two arrays. Instead of relying on the storage properties of the arrays to make the correlation, the arrays can be read into a small memory for comparison. Each array is exposed for only a short period of time. The invention includes apparatus for controlling the time interval between the exposures.
