Abstract

The invention discloses a tactile sensing device based on coding hole imaging technology, which includes: a sensing unit, a coding hole unit, a photoelectric conversion unit and a support frame structure unit, wherein the sensing unit is arranged on the outermost layer and is used to control the touch behavior The resulting physical changes are converted into visible changes by optical means; the coded hole unit is set on the inner layer of the sensing unit, which is a plane or non-planar coded aperture plate, and the coded aperture plate is equipped with one or more optional point light sources , used to generate multiple coded aperture images through the switching of point light sources; the photoelectric conversion unit is arranged in the innermost layer, used to convert the coded aperture images into electrical signals; The conversion unit provides stable structural support. The tactile sensing device has a simple and compact structure and is easy to process.

Description

technical field [0001] The invention relates to the technical field of tactile sensors, in particular to a tactile sensing device based on coding hole imaging technology. Background technique [0002] The tactile sensor based on the optical principle is rich in information, high in precision, and has various sensing capabilities of pressure, sliding, and cold and heat. However, in related technologies, the processing and manufacturing process is complicated, the volume is relatively large, the micro-lens is more precise, and there are a series of shortcomings such as not being resistant to shocks and temperature changes, such as: [0003] Invention patent CN201410301656.7 "Optical flexible two-dimensional tangential force tactile sensor" discloses a sensor composed of a light source layer, a polymer flexible conductive layer and a photodetection layer, and the photocurrent change of a 2×2 array photodetector , to measure the magnitude and direction of the two-dimensional ta...
