Abstract

The invention relates to a non-contact angle / placement detection sensor, belonging to the technical field of photoelectron, and comprising a shell. The center of the shell is provided with a rotating shaft, and the tail end of the shell is provided with a cover plate. The non-contact angle / placement detection sensor is characterized in that an image sampling processing system is fixedly mounted in the shell, the rotating shaft is provided with a reflecting plate, and the shell is also provided with a signal output interface connected with the image sampling processing system. The invention adopts a novel photoelectric conversion principle to combine an image detection technique with a singlechip information processing technique to design the small-sized angle / placement detection sensor, and the small-sized angle / placement detection sensor has the advantages of low cost, small volume, high precision, stable property, and the like, can replace the prior sliding regulation resistor and the prior photoelectric encoder which have most applications and extensive purposes and extensively applied to aspects such as control regulation, angel detection, microspur displacement detection, revolution counting, and the like.

Description

(1) Technical field: [0001] The invention relates to the field of optoelectronic technology, and is a non-contact angle / displacement detection sensor. (two) background technology: [0002] At present, sliding potentiometers and encoders are generally used for angular displacement detection. The sliding potentiometer has the defects of small adjustment angle, poor linearity, mechanical wear and tear, and it is in the form of analog output; and the encoder has two types: mechanical encoder and photoelectric encoder. The photoelectric encoder is composed of a grating disk and a photoelectric detection device, and converts the mechanical geometric displacement on the output shaft into pulse or digital quantity through photoelectric conversion. The grating disk is a disk with several rectangular holes equally divided on a circular plate with a certain diameter. Since the grating disk is coaxial with the rotating handle, when the rotating handle rotates, the grating disk rotates ...
