ABSTRACT:
An improved oculometer yielding simplified data accumulation and reduction techniques because of the use of a cylindrical lens system which optically integrates the light reflected from the eye being studied. The use of the cylindrical lens system and a linear sensing element reduces the location data required by a factor of a square root and makes digital processing of the information practical.
