25 December 1979 Two-Wavelength Contouring With The Automated Thermoplastic Holographic Camera
Author Affiliations +
Two-wavelength holography has been demonstrated to be a useful tool for contour mapping of three-dimensional objects. The combination of a tunable dye laser with a thermoplastic device allows the mapping of a diffused object in any desirable contour spacing in near real-time measurement. This paper describes such a combination using a newly developed thermoplastic holographic camera. The performance of this camera will be demonstrated by showing several examples of TWH contouring.
