映像投影装置
Document Type and Number:
Japanese Patent JP7400730
Kind Code:
B2
Abstract:
A purpose is to provide a technology for improving the resolution and/or the angle of view of an image projection device including a scanning mirror. The present technology provides an image projection device including an optical waveguide element including at least one incident port on which a laser beam is incident and a plurality of emission ports from which the laser beam is emitted, and a scanning mirror that performs scanning with the laser beam emitted from the optical waveguide element, in which the laser beam with which the scanning mirror performs the scanning reaches a projection target. According to one embodiment of the present technology, the image projection device may further include a hologram element that condenses the laser beam with which the scanning mirror performs the scanning on a vicinity of a pupil to allow the laser beam to reach a retina. According to another embodiment of the present technology, the image device may allow the laser beam with which the scanning mirror performs the scanning to reach a projection surface without or through a projection optical system.
