Abstract (en)
[origin: ES8704021A1] A device and installation are provided for the instantaneous and simultaneous detection, inside and outside, of radiations emitted in the infrared, visible and ultraviolet spectra by simultaneous physical phenomena having a character of risk, such as intrusion, fire, explosion, leaks of dangerous fluids and electric leaks, disturbances and absence of movement of a regular periodic phemonenon, said radiations being emitted, directly by the phenmonena to be monitored at the time when the risk appears or being caused artifically by directing over an appropriate field of view, in which take place said phemonena, a source of radiation comprised in the infrared, visible and ultraviolet, and adapted to the nature of the phemonena involved, said field of view covered by the detection device having appropriate horizontal and vertical dimensions comprising at least one spectral correction filter known pass band chosen as a function of the nature of the radiation, a linear or circular polarization filter, a microprism array, and an image booster. An installation utilizing at least one detection device is disclosed, where the detection device cooperates with at least one video data processing unit, at least one video monitor, each associated to a detection device, a time delay unit, a cyclic switch, a video tape recorder and a television telephone transmitter.
Abstract (fr)
La présente invention est relative à une installation de détection instantanée d'un ou plusieurs phénomènes physiques. Le dispositif se caractérise en ce qu'il est constitué par une caméra de télévision équipée de: au moins un filtre de correction spectrale (1a, 1b) à bande passante connue choisie en fonction de la nature du rayonnement, un filtre (2) de polarisation linéaire ou circulaire, un réseau de microprismes (3), un intensificateur d'image (5). Application à la détection de phénomènes physiques ayant un caractère de risque et notamment détection d'incendie.
