FIELD: measurement technology.
SUBSTANCE: sensor has tactile part and image forming aid. Tactile part of sensor has transparent flexible case and many groups of markers disposed inside flexible case. Any group of markers is made of many dyed markers. Markers composing different groups have different color in any group. Behavior of dyed markers is photographed by means of image forming aid in case when object touches flexible case. Different groups of markers preferably have different spatial disposition. Measurement is carried out by means of multi-channel reading-out which uses color or optical spectrum for tactile optical sensor to get info for many degrees of freedom at any point on surface.
EFFECT: improved precision of measurement.
