ABSTRACT:
A method of measuring locally specific pressures with an instrument that employs a matrix of intersecting columns and lines, each consisiting of pressure-transmitting conductors. The conductors are optical fibers. The column-associated optical fibers and the line-associated optical fibers are arrayed such that a locally specific pressure at their point of intersection produces an area of contact of different size. Light is introduced at at least one end of only a single column-associated or line-associated optical fiber. The amount of light coupled in at the points of intersection is read out at all optical fibers intersecting these optical fibers. The result is a locally specific distribution of pressure.
