PRELIMINARY DEVELOPMENT AND TEST OF AN INFRARED WATER LEVEL PICKUP

Abstract

The pickup is designed to sense the motion of a distant light source. It consists of a wheel driven by a constant speed motor, a fixed visible light and two photo cells sensitive respectively to visible and infrared light. Tests in the laboratory indicate that the pickup can measure with acceptable accuracy the change in the vertical position of a light at a distance of 3 feet when the rate of change of position if from 0.0 to 0.1 cycles per second. The observation distance is limited by the sensitivity of the photo cells used.
