摘　　要：设计了一套照明CAD软件用于实现对光学仪器中照明光路照度分布模拟。对该照明CAD系统的光线追迹与光照度计算方法进行了理论探讨,其中在光照度计算方法中引入了线性同余组合发生器,大大提高了模拟的真实性。运用该软件对实际照明光路进行了分析,分析结果表明该软件获得了需要的照度分布模拟图,能较好地满足用户要求。An illumination CAD software is designed to simulate the illuminance distribution of the optical path in the optical instruments. The ray trace and the illuminance calculation method of the CAD system is analyzed. And the linear congruence generator is introduced in the calculation, which improves the emulation reliability. An illumination system is analyzed with this software. The simulation results show that the illuminance distribution simulation is acquired by this software, and it satisfies the request of users.
