Title (EN) A HEAD UP DISPLAY WITH AN ANGLED LIGHT PIPE
(FR) COLLIMATEUR TÊTE HAUTE AVEC UN CONDUIT DE LUMIÈRE INCLINÉ
Abstract:
(EN) A head up display includes a light pipe and a waveguide combiner. The light pipe is configured to expand a pupil in a first direction and includes an input grating and an output put grating. The light pipe also includes four elongated surfaces, and the input grating and the output grating are provided in one or more planes parallel to two of the elongated surfaces. The waveguide combiner is configured to expand the pupil in a second direction perpendicular to the first direction. The first light pipe is disposed at an angle with respect to a waveguide combiner.
(FR) Un collimateur tête haute comprend un tuyau de lumière et un combinateur de guide d'ondes. Le conduit de lumière est conçu pour dilater une pupille dans une première direction et comprend un réseau d'entrée et un réseau de sortie de sortie. Le tuyau de lumière comprend également quatre surfaces allongées, et le réseau d'entrée et le réseau de sortie sont disposés dans un ou plusieurs plans parallèles à deux des surfaces allongées. Le combinateur de guide d'ondes est conçu pour dilater la pupille dans une seconde direction perpendiculaire à la première direction. Le premier tuyau de lumière est disposé à un certain angle par rapport à un combinateur de guide d'ondes.
