Abstract
This invention is a two-dimensional pressure sensor which can be used to determine a pressure distribution across a two-dimensional object which comes in contact with the sensor. The sensor includes a light source, a matrix of light transmitting fiber endings which includes an alternate pattern of transmitting and receiving light fibers, a transmitting fiber sub-array located a distance from the matrix and composed of transmitting fibers, a receiving fiber sub-array located a distance from the matrix and composed of receiving fibers, a semi-transparent deformable medium located above the matrix, a retro-reflective material located on top of the deformable medium, a flexible membrane located adjacent said retro-reflective material and positioned to contact an object, and apparatus such as a photodetector array, for detecting light which is reflected by the retro-reflective material and transmitted to the receiving fiber sub-array.
