A SEA SURFACE SIMULATOR. I. THEORETICAL ANALYSIS: SIMULATION OF REFLECTANCE PROPERTIES OF THE SEA SURFACE BY ARRAYS OF ERGODIC CUPS,

Abstract

The surface of the sea provides the background against which all floating objects are seen by observers aloft. The luminance of this background depends upon the lighting and upon the sea-state. Measurements of the apparent luminance of the sea from aircraft are possible but expensive. A sea surface simulator has been devised which enables the luminance distribution of the sea surface to be measured under any outdoor lighting conditions without the presence of an ocean and without an airborne photometer.
