    摘要： A display apparatus of the present technique includes a display unit configured to project an image onto a light transmissive display member, and forms a virtual image, of the image projected by the display unit, on an opposite side of the display member to a user. The display unit is configured such that a display device for displaying an image and a projection optical system for projecting the image displayed on the display device onto the display member are housed in a housing having an opening through which projection light is emitted. The projection optical system includes, on an optical path from the display device to the opening, a first reflection member disposed on a display device side and a second reflection member disposed on an opening side. The first reflection member has a reflection surface which reflects the image displayed on the display device and has a convex shape, and the second reflection member has a reflection surface which projects the image onto the display member and has a free curved concave shape. Further, a relationship between vertical length Yv of the image displayed on the display device and distance T, on a central optical path, from the user to the virtual image satisfies 0.03

    摘要： A projection optical system (10) is an optical system that projects from a first image plane (5) on a reducing side to a second image plane (6) on an enlargement side. The projection optical system (10) includes a first optical system (11) that includes a plurality of lenses and forms a first intermediate image (51) formed inside the first optical system (11) by light incident from the reducing side into a second intermediate image (52) on the enlargement side of the first optical system (11); a second optical system (12) that includes a first reflective surface (M1) with positive refractive power which is positioned further to the enlargement side than the second intermediate image (52); and a glass block (30) that is disposed between the first optical system (11) and the first reflective surface (M1), the glass block (30) passing light rays from the first optical system (11) to the second intermediate image (52).

    摘要： An optical device is disclosed. An optical device of the present invention that generates a depth map for an object comprises: a projector for irradiating electromagnetic waves onto an object; an optical receiver for receiving reflected waves reflected from the object; and a processor for generating a first depth map for the object on the basis of the direction of arrival of the received reflected waves, generating a second depth map for the object on the basis of the arrival time of the received reflected waves, and combining the first depth map and the second depth map and generating a depth map for the object.
