Abstract
The invention concerns an optical instrument, designed to be used on a satellite, for simultaneously or quasi-simultaneously observing in two opposite angularly separated directions. It comprises at least two telescopes (TA, TB) having angularly spaced apart observation directions, each having a real and accessible exit pupil and respective planar or superimposable image fields, with a width at least five times more than that of the pupil in a specific direction. Optical means provided at the exit pupil are arranged so as to form the image fields in a common overlapping focal plane except in lateral zones whereof the width is substantially equal to that of the exit pupil of the telescopes. In the common focal plane, an assembly of several matrix detectors are arranged and oriented on the superimposition zone of the image fields of the telescopes in the wavefront.
