DISPOSITIF OPTIQUE, FIXE SUR MONTURE DE LUNETTES, POUR VOIR DERRIERE SOI SANS AVOIR A SE RETOURNER

摘要

The device has two interactive mirrors (m, M) whose crew is fixed on a frame of spectacles. The two mirrors are dimensioned in a rectangular shape. A plane of one of the two mirrors is vertical and placed between a nose and an eye at a distance of 2 cm from a symmetry mounting plane. A plane of the other mirror horizontally swivels around a clevis pin. The planes of the two mirrors are vertically oriented relative to each other. A visual beam output from the latter mirror is parallel to an output from an eyeball when the eye is directed on a center part of the former mirror.
