Design of Medical Laser Detector Optical System

In order to satisfy the functional request of medical laser detector, the system theory of laser medical detector is analyzed. The gradual correction method is used in the design of laser transmitting and receiving optical system. The variable beam lens system is adopted in the transmitting system, and the Galileo telescope system is used in the receiving system. The software Zemax is used to simulate and macro language ZPL to write program, and the spot diagram and the structure chart of the transmitting and receiving optical system are get. In this design, the transmitting and receiving optical system is non-coaxial. There is a certain distance between two optical axes. So in order to ensure the two coaxial, splitting prisms are used to connect the transmitter optical system and the receiving optical system, forming combined optical system.
