Quantum efficiency of the eye determined by comparison with a TV camera

Abstract

The corneal quantum efficiency of the eye was evaluated by comparing perception of a test chart using dark-adapted vision, with the perception of the same chart using an I-SIT TV camera and a monitor. Monochromatic radiation was used for the test. Irradiance of the scene was balanced for the two perception methods so that the same chart information was observed in both cases. The quantum efficiency of the eye was then deduced from the ratio of the two irradiance levels, the apertures of the eye and of the camera lens, and the quantum efficiency of the first photocathode of the I-SIT tube. Several subjects were tested; the results showed the quantum efficiency of the eye to be in the range 1% to 4%. The experiment was limited to radiation levels equivalent to starlight and two orders of magnitude higher.
