Abstract
We present a 3-D holographic inspection device for laboratory and industrial use. The photosensitive recording medium is a thermoplastic film with an effective aperture size of 70 x 50 mm. The physics of holographic recording on a thermoplastic film is well-known. This medium has numerous advantages over traditionnaly used holographic recording media : it is efficient, cheap and allows for dry, in-situ processing. However many technical problems had to be solved in order to develop an easy-to-use thermoplastic holographic camera. We will describe this camera and give some examples of its use for non destructive testing in laboratory and industrial environment. We will also point out the future possible developments of this device and the specific improvements we are expecting, in particular in the processing of the interference fringe pattern.
