Outline of Final Research Achievements

We proposed a wearable display with integrated holographic imaging elements (HIEs) obtained the scene images for easy recognition to low vision people and the images for the measurement of the distance measurement from user to the forward obstacle. In the previous work, we investigated the imaging characteristics of the transmitted-type HIE. In this work, we investigate the HIE with high diffractive efficiency on different wavelength range from the HIE for low vision people in order to obtain images for the measurement of the distance to the forward obstacle. Experimental results show that the imaging system with the HIE for the measurement of the distance measurement can obtain images the targets as a forward obstacle independently.
