Abstract
A transducer device for translating increments of linear displacement by means of opto-electronic sensing into increments of units expressed into units of volts. The device comprises an opto-electronic system, having a pair of co-planar, adjacently disposed radiation sensitive surfaces of square configuration, and a thereto facing, closely spaced surface of rectangular configuration being designed to emit a uniform pattern of radiation over its entire active surface. Wherein, the geometry of the emissive and sensing surfaces during relative movement provide a ratio of produced volt equivalent to the ratio of relative displacement between the emissive and sensing surfaces.
