Compact holographic camera without vibration insulation using a 670-nm semiconductor laser.

A compact camera for holography and holographic interferometry is presented. Owing to its simple and rigid construction, vibration insulation is not necessary. The use of a semiconductor laser with a wavelength of 670 nm permits the use of common holographic recording materials. The only optical components of this camera are a beam splitter and a deflection mirror. As an example of the application of this camera, holographic surface contouring is demonstrated.
