Title: Accessories for stereoradiography and stereoradioscopy
IPC: G03B35/00
Filed: 1984-05-25
Abstract: The device produces a stereoscopic image, on a single film or screen, of any object or person examined with X-rays, and reads the image. It comprises the following: a. A system G1 for producing the image: either a grid consisting of bands alternately opaque and transparent to X-rays, positioned in such a way as to define on the film or screen bands printed alternately by only one of the X-ray foci FO1 and FO2; or elements superimposing on the television screen two complete, differently coloured images determined by each of the two X-ray foci. b. An associated system G2 enabling each eye of the observer to see only the single image intended for it: either a grid with positioning devices formed by bands alternately opaque and transparent to light, or polarising the light alternately in crossed directions and reading with polarised spectacles; or reading with coloured spectacles. The device is suitable for any standard installation without affecting normal use and can be used in the most varied fields.

Title: Detection and deception prevention method for thermal imaging camera
Inventor: FOUILLOY JEAN PIERRE
IPC: F41G7/22
Filed: 1986-07-02
Abstract: The method involves use of a detection prevention device which includes a specialised detector which is separate from the camera and covers the same field as the camera. A spectral analyser detects high luminance monochromatic sources e.g. lasers which are directed towards the camera. The camera sweep is stopped on detection of the monochromatic source and an echo is produced.  The deception prevention device includes a different detector which is also distinct from the camera and which detects high power deception pulses. The sensitivity of the camera is reduced for the pulse duration so it is not detected or blinded and allows detection of laser sources in their real positions.
