设计了一种应用于瞬时热量标定系统的太阳模拟器光学系统，系统由短弧氙灯、椭球聚光镜和通道反射式积分器组成。介绍了椭球聚光镜的设计准则和限制要求，分析了积分器的工作原理和体均匀性，讨论了辐照面大小要求和安装空间的限制，最后，优化了系统设计并进行了仿真模拟。仿真结果表明，当选用近轴收大倍率为4．5、积分器管长为85mm时，若采用7000w氙灯，即能够获得3％的均匀性和4250食太阳常数的辐账“瞍；若采用5000W氙灯，则可在均匀性不变的情况下获得2980个太阳常数的辐照强度，两者均满足使用要求。

The optical system of a solar simulator used for a transient calorimeter calibration system is de- signed, which comprises a Xe are, an ellipsoidal specular reflector and a channel optical integrator. The de- sign criteria and limitations of the ellipsoidal specular reflector are introduced, and the work principle and spa- tial uniformity of the integrator are also analyzed. Then, based on the sizes of receiving surface and installation space, the system design is optimized and simulated. The simulation results show when the amplification factor and the length of the integrator are set to be 4.5 and 8.5 mm respectively, the received average flux will be 4 250 sun constants with a radiation uniformity below 3% for a 7 000 W Xe arc lamp, and 2980 sun constants with the same radiation unformity for a 5 000 W arc lamp. Both of them can meet the operating requirements of the transient calorimeter calibration.
