Filed: 2009-04-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide an HOE which can be applied to a video display device, an HMD and HUD with large observation angles, ensures high image quality over the whole screen, and allows bright video images to be observed.  <P>SOLUTION: In the reflective and volume phase type HOE, half value width of diffraction wavelength is different depending on an area in the surface. The HOE is attained, for example, by differentiating film thickness depending on the area, or differentiating conditions (for example, exposure, heat treatment temperature, heat treatment time) depending on the area. An influence of chromatic dispersion of the HOE to light which passes through surrounding parts of the HOE is reduced even when the HOE is used so as to be incidence/reflection characteristics near regular reflection at a center part of the HOE by making the half value width at the surrounding parts of the HOE narrower than that at the center part. Consequently, the HOE becomes suitable for the video display device with the large observation angle of view in which the influence of the chromatic dispersion of the HOE in the surroundings of a screen cannot be ignored.  <P>COPYRIGHT: (C)2011,JPO&INPIT
