CA 2533549

A viewing instrument having a variable direction of view is disclosed generally comprising a shaft, a sensor mounted in the distal end of the shaft such that the image plane of the sensor is substantially parallel to the longitudinal axis of the shaft, and a reflecting element that rotates about an axis substantially perpendicular to the longitudinal axis of the shaft. In some embodiments, a negative lens is mounted adjacent the reflecting element, and in certain embodiments, a positive lens is positioned adjacent the image sensor.

Instrument à angle de vue variable qui comprend généralement un arbre, un capteur fixé à l'extrémité distale de l'arbre de sorte que le plan d'image du capteur soit sensiblement parallèle à l'axe longitudinal de l'arbre, et un élément réfléchissant qui tourne autour d'un axe sensiblement perpendiculaire à l'axe longitudinal de l'arbre. Dans certains modes de réalisation, une lentille négative est fixée à proximité de l'élément réfléchissant, et dans certains modes de réalisation, une lentille positive est placée de manière adjacente au capteur d'image.
