Problems solved by technology

Common self-collimation detection and assembly methods (Gao Tianyuan, Research on the structural design and assembly method of sub-aperture splicing imaging system [D], Changchun: Changchun University of Science and Technology, 2012, 53-58) require high-precision plane mirrors and matching references The light source and detector have high detection and assembly accuracy, but they are sensitive to environmental factors, and the required tools have high precision and high requirements for the working environment
The method of inspection and assembly using tools such as micro-collimation telescopes and high-precision auxiliary tooling (Li Depei. Adjustment and inspection of astronomical optical telescopes [J]. Optical Technology, 1998, 24(3): 27-31), Inspection and assembly The accuracy is high, but the workload is heavy, the required tooling is various, and a large number of personnel are required to cooperate

Abstract

A method for quickly assembling and adjusting an axisymmetric telescope with the image plane as a datum provided by the invention comprises the following main steps: (1) a visual axis datum which is perpendicular to the image plane and passes through the center of the image plane is established by using an outgoing beam; (2) the secondary mirror is assembled and adjusted based on the fact that thenormal vector of the vertex of the secondary mirror coincides with the optical axis; and (3) a cross wire is drawn between the primary and secondary mirrors of the telescope, and the primary mirror is assembled and adjusted based on the spin symmetry of an axisymmetric optical system. The tools used for assembly and adjustment have the following characteristics: (1) a laser is used to produce anoutgoing beam as a reference beam; (2) the outgoing beam can rotate with high precision; and (3) high-precision tilt adjustment can be carried out on the outgoing beam around a point on the axis of rotation, and the axis where the outgoing beam is located passes through the tilt adjustment center. The method of the invention is suitable for quickly assembling and adjusting an axisymmetric telescope, and can also be used for installing a transmission optical module. The assembling and adjusting tools are simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of optical telescope detection and assembly, and relates to a technical method for optical telescope assembly and adjustment. Specifically, certain tools and methods are used to quickly complete the low-precision optical assembly and adjustment work of the telescope. Background technique [0002] At present, in the field of optical telescope detection and assembly technology, the method of adjusting optical telescopes is to first complete the design and processing of a telescope, and only after completing the assembly and adjustment according to a certain technical method can it work normally. The main task of telescope assembly and adjustment is to ensure that each optical component is in the space position required by the design. Conventional assembly and adjustment methods require micro-collimation telescopes, pentaprisms, micro-adjustment platforms, etc., as well as a large number of tooling. The worklo...
