In the Measurement System-1 (see Fig. 1 (a), (b)), measure the reflection ratio of "White" and "Black"
respectively and calculate by using the formula (2).
CR =
In the Measurement System-2 (see Fig. 2), measure the white chromaticity. The light source and viewing
area are D65 and 2° respectively.
In the Measurement System-3 (see Fig. 3), measure the electro-optical response time.
