Two-dimensional scanning device for microscopes

Abstract

The invention provides a two-dimensional scanning device for microscopes, comprising a scanning microscope, a control part and a two-dimensional scanning part. The control part and the two-dimensionalscanning part are arranged on the scanning microscope, and the control part is electrically connected with the scanning microscope and the two-dimensional scanning part. The control part comprises anexternal synchronization signal interface, a phase-locked loop and a servo motor controller. The output end of the external synchronization signal interface is electrically connected with the input end of the phase-locked loop, and the output end of the phase locked loop is electrically connected with the input end of the servo motor controller. The two-dimensional scanning part comprises a polygonal mirror, a reflector and a motor. The device has a simple structure. Two-dimensional uniform and efficient scanning can be realized for microscopes, and problems such as sample overexposure and dye bleaching caused by slow scanning can be avoided. Moreover, there is no return blanking time of field scanning, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of scanning equipment, in particular to a two-dimensional scanning device for a microscope. Background technique [0002] In the research and development process of universities and enterprises, the microscope is an auxiliary equipment to realize the observation of living biological samples and their rapidly changing physiological activities. The continuous development of technology has also put forward higher requirements for the scanning speed of the microscope. However, the existing scanners for microscopes have the following problems in the actual use process: [0003] 1. At present, commercial microscopes generally use a resonant scanner with a resonant frequency of 7.8KHz to scan the object in the X direction, which can achieve 512x512@30fps imaging capability. For 512x32@400+fps, it needs to be completed by compressing the number of lines per frame Imaging requirements, and the imaging range at this ...
