Title
(EN) OPTICAL IMAGE SEPARATOR
(FR) SEPARATEUR D'IMAGE OPTIQUE
Abstract
(EN)
An optical assembly divides a single image into a plurality of images which are simultaneously projected onto a single sensor array. The optical assembly is arranged so that the plurality of images can be made to pass through a filter (9, 10) of a different type. For example a polarizing filter of a different orientation, or a filter which passes a different spectral band. In this way a single digital camera having a single chip sensor array can simultaneously receive multiple and substantially identical images which have been acted on by different filters. This allows data capture from a single frame of a single camera to be used to perform stress analysis, or spectral analysis. This is particularly useful when high speed image capture is desired which contains stress or spectral data, because each frame captured from the sensor array contains multiple images which can be processed to obtain stress or spectral data.

L'invention concerne un ensemble optique divisant une image unique en plusieurs images projetées simultanément sur une mosaïque de capteurs unique. L'ensemble optique est disposé de manière que les images puisse passer à travers un filtre (9, 10) de type différent. Un filtre de polarisation, par exemple, d'orientation différente, ou un filtre passant une bande spectrale différente. De cette façon, un appareil photo numérique unique possédant une mosaïque de capteurs à une seule puce peut simultanément recevoir plusieurs images sensiblement identiques lesquelles ont été traitées par différents filtres. Ceci permet de capturer des données d'une prise de vue unique d'un appareil photo unique utile dans l'exécution d'analyse de contrainte, ou d'analyse spectrale. Ceci est particulièrement utile lorsque l'on désire capturer des images à grande vitesse, lesquelles contiennent des données de contraintes ou des données spectrales, parce que chaque prise de vue capturée par la mosaïque de capteurs contient plusieurs images pouvant être traitées en vue d'obtenir des données de contraintes ou des données spectrales.
