Abstract

The invention provides a hyperboloid lens-based angle sensor and a measuring method thereof. The angle sensor comprises a first photoelectric detector, a second photoelectric detector, a first hyperboloid lens and a second hyperboloid lens, and the first hyperboloid lens is arranged between the first photoelectric detector and a transmitting part. In the process of measurement in which a light beam is transmitted to the same photoelectric detector via a light-transmitting hole, the light beam which emerges from the light-transmitting hole enters the first hyperboloid lens, is transmitted by the first hyperboloid lens, and then enters the first photoelectric detector; and a processing system obtains the rotational angle value of a measured object by processing according to the incident position change value of the light beam received by the first photoelectric detector and / or the second photoelectric detector. The novel angle sensor can continuously measure angle, moreover, the precision is high, and the speed of computation is high.

Description

technical field [0001] The invention relates to the technical field of precision testing, in particular to an angle sensor based on a hyperboloid lens and a measuring method thereof. Background technique [0002] Angle sensor is a commonly used geometric quantity sensor, which is widely used in many fields such as aerospace, industrial production, machinery manufacturing and military science. Such as figure 1 As shown, the patent number is 201510276409.0, and the Chinese patent titled "A Continuous Incremental Optical Arm Amplified High-precision Angle Sensor" discloses an angle sensor. The sensor has a simple structure and is suitable for continuous increment of the measured object angle. Change measurement, reliable measurement, easy to achieve mass production. According to the basic principle of optical arm amplified continuous angle measurement, the calculation process of the angle sensor is complex and time-consuming, and there are nonlinear errors in the system, resu...
