By placing a spectrograph sensor at the 100 cm position, Geola was able to measure the peak sensitivity and signal:noise ratio of the screen and compare this with a standard white front-projection screen (with 75% reflectance).
The results are shown in the table below, and it can be seen that while the peak sensitivity varied from a standard screen, the signal:noise ratio of the holographic screen is significantly better.
