Title (EN) PHASE DETECTION DEFLECTOMETER-TYPE OPTICAL DEVICE HAVING A LARGE MEASURING RANGE
(FR) DISPOSITIF OPTIQUE DU TYPE DEFLECTOMETRE, NOTAMMENT A DETECTION DE PHASE, A GRAND DOMAINE DE MESURE
Abstract: front page image
(EN)A phase detection deflectometer-type optical device. Between the grating and the CCD camera, a primary lens (19) with a large entrance pupil provides an intermediate image on a ground glass (20), and the intermediate image passes through a secondary optical member (21) which uses it to form a final image on the sensor (6) of the CCD camera.
(FR)Dispositif optique du type déflectomètre à détection de phase. Entre le réseau et la caméra CCD, un objectif primaire (19) à grande pupille d'entrée fournit une image intermédiaire sur un dépoli (20); et un système optique secondaire (21) reprend l'image intermédiaire et en forme une image finale sur le capteur (6) de la caméra CCD.
