Publication number: 20140354952Abstract: Disclosed is a system and device for observation of an eye (E) comprising a light source (LSo) for illuminating the eye. Further, the system includes a diffraction grating as an optical relay (OR) for receiving the light reflected from the eye and for deflecting it towards a light sensor (LSe). The incident light ray (r inc) intersects the optical relay at an incidence angle (alphajnc) with the normal (n_OR) to the optical relay in an incidence plane (Pl_inc) formed by the incident light ray (r_inc) and the normal (n_OR). The deflected light ray (r def) forms a deflection angle (alpha def) with the normal (n_OR) in a deflection plane (Pl def) formed by the deflected light ray (r_def) and the normal (n_OR). The optical relay is positioned such that the incidence and the deflection angle and/or the incidence plane and the deflection plane are different from each other.Type: ApplicationFiled: January 17, 2013Publication date: December 4, 2014Applicant: UNIVERSITE DE LIEGEInventors: Jacques Verly, Serge Habraken, Jérôme Wertz

Patent number: 7319189Abstract: A space solar concentrator based on deployable reflectors attached to a panel base is described. Each of the reflectors includes sides coated with reflective coating on surfaces facing away from the base. In one embodiment, the sides of the reflector have thicker portion to provide stiffness for deployment absent compressive force, and thinner portion to reduce weight and storage energy. In another embodiment, both reflective sides are unfolded when the reflectors are in stowed position. During deployment, a stop side will limit the deployment of both reflective sides and ensure the proper reflecting position. In addition, these embodiments reduce the storage energy.Type: GrantFiled: October 27, 2004Date of Patent: January 15, 2008Assignee: Universite de LiegeInventors: Vincent Ruelle, Serge Habraken, Jean-Paul Collette

Patent number: 6528716Abstract: A space solar concentrator based on light-weight reflectors (3) attached to a honeycomb panel (1) is described. The integration of the reflectors (3) allows for a high modularity. Solar panel deployment is not perturbed by the reflectors (3) even with two-dimensional deployment concept. Each reflector (3) consists in small saw tooth aligned as rows (2) with solar cell rows in between. Low concentration is achieved with a high level of thermal control and a high optical efficiency. When small off-pointing occurs, the solar flux distribution is still the same on each cells. It guarantees a good electrical control and management on the whole panel. The reflectors (3) are preferably made of a thin film tight on a light-weight rigid frame deployed after launch. In another embodiment, the reflector is not deployable and is part of the panel substrate. A stowed configuration allows for superimposition of the solar panel.Type: GrantFiled: July 20, 2001Date of Patent: March 4, 2003Assignee: Universite de LiegeInventors: Jean-Paul Collette, Jean-Marc Defise, Serge Habraken
