Multi-target optical fiber position accurate detection and positioning system and method

Abstract

The invention discloses a multi-target optical fiber position accurate detection system and method, and belongs to the field of optical fiber position sensing technologies and optical fiber spectrum telescopes. The system comprises an image acquisition system, an illumination light source and an image data processing system. Each optical fiber double-rotation robot on the optical fiber spectrum astronomical telescope is provided with a white circular ceramic head, and the incident end of the optical fiber core is arranged at the circle center of the circular ceramic head. The illumination light source uniformly irradiates the ceramic head, and the image acquisition system identifies the optical fiber mounting plane. The method is mainly applied to a multi-target optical fiber spectrum telescope, the spatial position of each optical fiber is accurately detected, a training set is created by using a machine learning method for training, the trained model is applied to preliminary identification of the optical fiber, and then a series of image processing technologies are applied to accurately position the optical fiber; the anti-interference performance is high, and an observation light path does not need to be shielded.

Description

technical field [0001] The invention relates to the field of optical fiber position sensing technology and optical fiber spectrum telescope, in particular to a multi-target optical fiber position accurate detection system and method. Background technique [0002] Existing fiber-optic spectroscopy astronomical telescopes are the main means of obtaining celestial body spectra; when fiber-optic spectroscopy telescopes are observing different sky areas, the images (spots) formed by celestial objects through the telescope fall on different positions of the focal plane, in order to receive as many The light energy to the celestial body, in addition to requiring the optical system of the telescope to have good performance, must also allow the incident end of each optical fiber on the focal plane to be accurately aligned with the image of the celestial body. The optical fiber position detection system detects the position of each optical fiber. The existing optical fiber position d...
