摘要： PROBLEM TO BE SOLVED: To impart security such as presenting video information to only a registered person by providing the function of imaging the irises or retina of his or her eyeballs and authenticating the person, on a head-mounted type image display device for directly projecting an image on retinas so as to be sensed as a virtual image, and to solve the problem that approximately half the light is lost when the light is transmitted through or reflected from the half mirror results in low utilization efficiency of light, though a means by which visible light and infrared light, which are dealt with corresponding functions using a half mirror, are mixed or separated on a single optical system has been before proposed as a means for integrally presenting the image display function and eyeball imaging function.
SOLUTION: The present invention provides a means for enabling a single optical system to have two functions, one for image display and the other for iris imaging while minimizing light loss, by using a visible light reflection/infrared transmission mirror 2-a or a visible light transmission/infrared light reflection mirror 2-b.
