Abstract: In order to improve the teaching quality of image conversion function of prism and lens

in engineer- ing optics，the model of panoramic aiming system is built by using TracePro software.

The changes of the image at various locations are clearly observed under combined rotation of

isosceles right angle prism and Daowei prism. The

virtual simulation results are consistent with the theory in textbooks. It can deepen students'

understanding of image conversion function of prism and lens，and enable them to master the optical

structure and the principle of panoram- ic aiming system so as to improve the teaching quality and

classroom efficiency，and to stimulate students' interest in optical system design and research.

The extensive development of optical virtual simulation should provide a use-

ful supplement for enriching the online and offline teaching of optical courses.

Key words: panoramic aiming system, virtual simulation, TracePro
