Luminance Probes for Contrast Measurements in Medical Displays

Badano A, Pappada S, Kelley EF, Flynn MJ, Martin S, Kanicki J

We report on a comparative study that examines four conic luminance probes in their ability to measure small-spot display contrast. We performed linear scans of a slit using a computer-controlled stage. We found that, although the probes were assembled according to the same design, small differences in their performance due to minor variations in materials and surfaces can be measured.
