An electronic heterodyne technique is being investigated for video (i.e., television rate and format) recording of interference patterns. In the heterodyne technique electro-optic modulation is used to introduce a sinusoidal phase shift between the beams of an interferometer. For phase modulation frequencies between 0.1 and 15 MHz an image dissector camera may be used to scan the resulting temporally modulated interference pattern. Heterodyne detection of the camera output is used to selectively record the interference pattern. An advantage of such synchronous recording is that it permits recording of low-contrast fringes in high ambient light conditions. In addition, the use of a vector scanned image dissector camera permits one to scan only certain selected points for rapid acquisition of selected interferometric data. Results will be presented for the recording of simple interference patterns. The application of this technique to the recording of holograms will be discussed.
