Abstract

A dual-beam reflectometer has been built for measuring the reflectance of a small spot on the ocular fundus. This spot, variable in diameter from 0.3 mm to 3 mm, can be located precisely in the fundus, and both the spot and a large area of the fundus can be observed during measurement. The reflectance is measured simultaneously for six wavelengths, in the region 4500–8000 Å, by using a rotating disk provided with interference filters. The time variations in reflectance of the spot are displayed on a recorder in logarithmic units.
