Retinal projection display using holographic optical element

We have already proposed that we could realize the see-through HMD by using the Holographic Optical Elements (HOEs). The HMD using HOE we proposed so far is used the Maxwellian View, which is the direct projection on the human retina. When we see something by the Maxwellian View, we don't need the focusing of the crystalline lens (ocular accommodation) because the depth field is extremely wide. We have been estimated the optical characteristics of this HOE by using still images on the slide mount. In this report, we will show the prototype of Retinal Projection Display, which can provide us the electrical dynamic images on the electrical spatial light modulator.
