Title:
画像表示装置、投射光学系、及び画像表示システム
Document Type and Number:
Japanese Patent JP7207405
Kind Code:
B2
Abstract:
An image display apparatus according to an aspect of the present technology includes a light source, an image generator, and a projection optical system. The image generator modulates light emitted from the light source and generates image light. The projection optical system includes a lens system and a concave reflective surface. The lens system is configured on a basis of a reference axis at a position on which the generated image light is incident, and has a positive refracting power as a whole. The concave reflective surface is configured on a basis of the reference axis, and reflects the image light emitted from the lens system toward a projection target. In addition, the concave reflective surface reflects at least one or more light beams included in the image light incident on the concave reflective surface, toward a direction that intersects with a direction along the reference axis at an angle of 80 degrees or more.
