【摘要】 针对微面积变倍观测要求,设计了一组双组元全动型变焦距光学系统。利用高斯光学计算公式建立了系统的数学模型,计算了变焦透镜组的运动曲线。通过软件仿真计算,验证了运动模型的正确性,并选定6x-16x放大倍率。利用空间凸轮机构实现6x-16x变焦系统机械结构。更多还原

【Abstract】 In this paper a dualistic both- moved zoom optical system is presented in order to meet the request of micro area zoom inspection. The article states the whole design idea: modeling mathematical system by Gauss formula, calculating zoom lens movement curve. The movement modeling of the zoom lenses is validated by data from result of real system. A zoom range of 6x -16x is selected. And a dimensional cam structure is employed here to realize the zoom range.更多还原
