To a supersonic missile
a seeker could enhance the aerodynamic ability due to decrease the resistance in flying. At the same time
the primary function of a seeker has been considered as the most important equipment for a missile
due to the importance for cueing of targets and tracking for the final approach. However
the dome of a seeker
which is made up of glass
has poor mechanical performance. Especially
in the higher altitude
for a dome
in which the aerothermal and pressure loads could destroy the structure easily
it is necessary to do the thermal-structure coupled analysis due to varied materials. In the paper
to take the spherical dome of a seeker as a example
the analysis has been completed according to the varied materials consist of MgF2
Al2O3 and ZnS. The temperature loads and the pressure loads derived from the results of fluent analysis has been forced on the surface of dome
which simulates the actual Mach 2.5 in flying. According to the results of coupled analysis
the SEQV stress of the dome radium 80mm based on three materials had reached to 31MPa
which shows that the strength is sufficient for Mach 2.5
and offered the warranty to design the attaching to missile for the dome. At the same time
the results required the flexible mounting for the dome due to the displacements results
which the crystal material couldn't accept. 2011 IEEE.

A review of high-speed flow pressure and aerodynamic heating effect on Supersonic missile's dome is given. The dome should have excellent properties in optical
mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome
a reasonable finite element model (FEM) of dome is established
and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on
through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section
and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis
a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward
which can reduce the stress concentration. 2009 SPIE.

Each disciplinary has its own modeling and analysis tools to solve its own specific field problems. In order to achieve integrated simulation of high precision space optical systems and predict optical performance respective to the mechanical and thermal loads
data must pass through different analysis tools. Simulation tools used in the thermal
structural and optical design process and the relationship among them were first depicted and the integrated simulation methods were described in detail. Zernike polynomial fitting methods and interpolating approaches were also demonstrated. Because of the orthogonality of Zernike polynomials
it was not probably used in some situations such as noncircular apertures and discrete data
and the coupling of Zernike polynomial coefficients and other methods were also introduced in the paper. The toolkit OMTIA (Optical
Mechanical and Thermal Integrated Analyzer) based on the methods was developed
which appears as an indispensable tool for engineering practice.

Profile error of super smooth surface of optical elements at X-ray/EUV in synchrotron radiation (SR) light beam line is described as slope error of them generally. The Long Trace Profiler (LPT) is used for testing surface slope error of SR optical elements in world generally. It is requisite to use In-suit LTP measuring surface thermal distortion of SR optical elements with high heat under high bright SR source. Authors design an In-suit LTP by means of co-path interferometer with pencil light beam. The instrument not only can be used for testing slope error of mirrors in Lab. also in situation test the distortion of mirror with high heat load at synchrotron light beam line. The device can be used to test various absolute surface figures of optical elements such as aspherieal
spherical and plane. It is needless standard reference surface. It is named by LTP-III. This paper describes its basic operating principle
