The present invention relates to an optical system including at least one objective lens () for receiving light from an object (), an array of image forming elements () for generating multiple images of the object on an image sensor plane (SP) and a filter (F). The optical system is configured to form a real image of the filter on the array of image forming elements to filter the multiple images of the object, the filter being arranged with respect to the at least one objective lens so that a real image of the filter is formed on the array of image forming elements, and wherein the optical system is configured to be telecentric in the image plane of the filter.

Optical system

A positioning system, in particular, six-dimensions positioning system of a shadow sensor with respect to a constellation of light sources is provided. The sensor can be a shadow sensor and has a mask and a 2D imager. By recording the shadow of the mask cast by each light source on the imager, and by properly multiplexing the light sources, the system can compute the 6D position of the shadow sensor with respect to the constellation of light sources. This computation is based, in part, on treating the shadow of the mask cast on the imager as the equivalent of the projection of light in a pinhole or projective camera. In one embodiment, the system is applied in a surgical domain. In another embodiment, the system is rapidly deployed.
