Retinal Projection Display Using Diffractive Optical Element

We have previously proposed a retinal projection head-mounted display (HMD) using the principles of the Maxwell Ian view. The principle of Maxwell Ian view can provide an image with a focal depth. In conventional HMD prototype, we have been using a holographic optical element (HOE) as an optical combiner. However, there are some problems with HOE. Therefore, in order to solve these problems, we propose the use of diffractive optical elements (DOE) of the phase-type based on computer-generated hologram (CGH). The paper show that phase-type DOE based on CGH is effective as retinal projection optical system.
