ABSTRACT:
A description is given of a tactile sensor for measuring force with fine resolution which is based on a network of glass fiber optic interferometers. The counting of interference fringes as readout method makes available an inherently digital (incremental) output signal which allows the measured signal to be passed on optically free of interference to evaluation electronics and to data processing. In conjunction with a suitable elastic skin to accept the glass fiber network, the small glass fiber diameter (125 .mu.) and the user of the strain measurement technique employing glass fiber interferometers should make possible a tactile sensor comparable with the human sense of touch. The fields of application for such tactile sensors are robotics, prostheses and advanced controls at the man-machine interface.
