The results show the imaging quality is near the diffraction-limitation and is stable. The designed system possesses good athermal and achromatic ability. ( 4) Design of off-axis three-mirror reflective optical system.
从结果看,该系统成像质量达到了衍射极限,成像质量稳定,体现了谐衍射元件消色差和消热差等性能。(4)离轴三反射镜光学系统研究。
Results show the imaging quality is near the diffraction-limitation in visible spectrum and arrived in infrared spectrum. So the off-axis three-mirror reflective is able to work in the multi-band from the visible spectral region to infrared range.
从评价结果来看,在可见光波段,像质接近衍射极限,在红外波段成像质量基本达到了衍射极限,充分说明了离轴三反射光学系统具备从可见光到红外多波段工作的能力。
