The measurement and assessment should be accompanied on any type of electronic displays. Especially, quantitative analysis is indispensable as the reference to catch the direction to proceed. In this paper, we will present the approach for quantification of the holographic display images. To do it, we achieved the holographic display system with spatial light modulator and Fourier lens, and adopted indices needed for evaluation, such as contrast ratio, cross talk, color dispersion, and uniformity. These indices have been generally employed in the field of classical 2D display and multi-view 3D display. However, there have been almost no tries to adopt them in that of holographic 3D display system due to the absence of concrete methodology up to now. We suggested a standard image, and identified that measured numbers could be used to select the better way of generating the holographic image. We believe that this quantitative approach for assessment of holographic images will help more accurate and systematic development in that field.
