Paper Abstract

Conformal optical dome can induce the drag of the missile. The conformal dome test is an important way to make the dome perfect for imaging. This paper shows a interference test of elliptical conformal dome's inside surface. First, the test system is designed by zero position method. The test system is composed by two parts: the focal lens and the spherical mirror. The interferometer used is operating in 632.8nm. The ideal test system's resolution is 0.0065waves in PV(peak to valley) value and 0.004 waves in RMS(root mean square) value. The next step is tolerance analysis. According to the optical and mechanical manufacture level, the tolerance analysis is done by optical software ZEMAX. The results are 1.219 waves in PV value and 0.249 in RMS value. The working wavelength is 4.2μm for conformal dome. After calculation, the PV value is 0.179 waves and the RMS value is 0.0366 waves. Finally, the bolster is designed, and for the key structure the topology optimizing is simulated
