Abstract: A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member, to provide a high quality virtual image displayed by a virtual image display device.

Abstract: A tunable optical filter utilizes a pair of diffraction gratings and a rotating mirror to achieve a broad filter passband or wavelength bandwidth. By adjusting a small angle between the two diffraction gratings, such as less than approximately 15 degrees, the wavelength bandwidth of the tunable optical filter's passband may be arbitrarily adjusted or set.
