Abstract

The variable focus telescope is utilized now in the laser transmitter system design. It changes the telescope's magnifying power in order to adjust the exit beam through moving the inner focus lens. This system has complicated structure and high machining expense. This paper investigates the focusing character of Gaussian beam through misadjust telescope and presents a new method for lidar transmission system design. The laser beam divergence angle and the radius of exit beam are changed through moving the distance between the back focus of object lens and the front focus of ocular. This design can provide a convenient method for calculating the focusing parameters. The restriction of assembly dimension and the effect of fitting and adjusting error which should be considered in engineering application are studied, and then bring a method to choose the right parameters of focusing optic system by the focusing requirement.
