摘要:
Eye-tracked head-mounted displays are provide which, in one aspect, may utilize the same optics for eyetracking and image viewing, with a selected portion of the optics used for an eyetracking optical path and a selected portion of the display optics used for an image viewing optical path.

Optical systems including an image surface, a stop surface, a partial reflector disposed between the image surface and the stop surface, a reflective polarizer disposed between the stop surface and the partial reflector, and a quarter wave retarder disposed between the reflective polarizer and the partial reflector are described. The reflective polarizer is convex along two orthogonal axes. The reflective polarizer may be a thermoformed multilayer reflective polarizer.

In a 1-2nd lens group, an aspheric resin lens is disposed on the outermost enlargement side, an enlargement-side fixed lens group (second fixed lens group) as a fixed group is disposed, a moving lens group, which move when focusing is performed in response to the magnification change, is disposed further on the reduction side from the second fixed lens group. Even in a case where the second optical group is configured of one mirror, it is possible for a primary image to have appropriate aberration and to hereby reduce aberration of an image which is finally projected onto a screen through the second optical group.

A projection optical apparatus capable of providing high image quality and having a reduced size is disclosed. The projection optical apparatus includes a light valve and a projection optical system including a first optical system having a transmissive-refractive element and a second optical system having a reflective-refractive element. An image formed on the light valve is projected by the projection optical system on a projection surface. The optical axis in the first optical system is folded both vertically and horizontally. The first group of the first optical system is contained in a space (dead space) whose lower limit is defined by a lower edge of the second optical system, thereby reducing the depth of the apparatus.
摘要:
L'invention concerne un dispositif adapté pour recevoir un flux lumineux incident comportant une première bande (λ1) de longueurs d'onde et une deuxième bande de longueurs d'onde, la première bande et la deuxième bande étant distinctes entre elles, comportant - un miroir primaire (M1), - un miroir secondaire (M2), - une première lame (21) semi-réfléchissante dichroïque, et - une deuxième lame (22) semi-réfléchissante dichroïque, le miroir primaire (M1) étant adapté pour recevoir le flux lumineux incident et le réfléchir vers le miroir secondaire (M2) ; le miroir secondaire (M2) étant adapté pour recevoir le flux lumineux à partir du miroir primaire (M1) et le réfléchir vers la première lame (21) semi-réfléchissante;
le dispositif comportant en outre un système de double coudage de la deuxième bande de longueurs d'onde. L'invention concerne également un système optique comportant un objectif bispectral et un dispositif précité.
摘要:
A projection optical system is disclosed. The projection optical system includes a first optical system configured to form a first image conjugated with an object and a second optical system configured to project a second image conjugated with the first image toward a projection surface. At least one of the first optical system and second optical system includes at least one optical element(s) movable relative to the object is provided. An image distance of the projection optical system is changed and a size of the second image is changed, by moving at least one of the optical element(s) relative to the object.
