DEVICE TO CREATE SENSOR SURFACE Russian patent published in 2013 - IPC G06F3/42 

FIELD: information technologies.

SUBSTANCE: device to create a sensor surface comprises the first and second radiators, an array comprising N optical receivers, a computing device and N receiving light guides, the first end of which is optically connected with one of optical receivers, and the second end is arranged along the line located in one plane with optical centres of the first and second radiators and is optically coupled with them, at the same time the sensor surface of the device represents a plane formed by crossing of radiation beams from the first and second radiator with the second ends of N optical fibres, and the computing device performs alternate connection of one of two radiators, input of signals from each of N photodetectors serially with the first and second connected radiator and calculates coordinates of the crossing point with a finger of a sensor surface operator.

EFFECT: simplified device and higher reliability of a device.
