球形屏恒面积视标投射式系统的研究

The Research of a Projeated System with Contant Areas Visal Mark

球形屏恒面积视标投射式系统是投射式全自动视野计的关键技术。介绍了一种恒面积视标投射式系统,阐述了其光学系统、扫描机构、视标大小补偿机构、控制系统等设计,叙述了其扫描控制算法。

The projected system with contant area's visal mark in a shere screen is critical technic for the full automatic projected perimeter. In this pape, the author introduces a projected system with contant area's visal mark and expounds the design of its optical system、scanning device、compensated organ for the size of visal mark and control unit etc. the arithmetic of scanning device is depicted too.
