The round raster is extensively applied in all kinds of high accuracy angular displacement measurement and control system. With the development of precise mechanotronics measuring instrument machining center CNC machine and various precise location testing technology a higher request is put forward to the accuracy and the function of raster measurement system. In this article it is concluded that double readheads is the most reasonable configuration scheme through tests of single readhead scheme two readheads and four readheads.

Modulation transfer function resulting from random vibration was analyzed. To conclude that the effect of angular displacement was the major factor. Allowable MTF degradation was represented and 34dB reduction was achieved at frequency of 100HZ. With the help of MSC.ADAMS simulation software and convert allowable MTF degradation into stable system design parameters simulated curve proves correct for isolator which can guide perfect design for stabilization system. Based on the spatial mechanism and translational principle of parallelogram and the irrotational displacement mechanism was tested by optical method an irrotational displacement isolator was developed. It can meet the requirements of irrotational displacement and damp. An instance was given coupled angle is less than 8? it can satisfy the demand of aerial imaging. (2011) Trans Tech Publications.

The opto-electronic platform is the main equipment for aviation reconnaissance. It is a surveillance system with the function of search recognition orientation and tracking by opto- electronic instruments. It is made up of opto-electronic instruments which are used to get high quality image and stabilization tracking system to control stabilization and gesture of platform for exact tracking. The opto-electronic platform purpose is to achieve high quality image. Besides the impact of optic system the image quality of the system is influenced greatly in the vibration environment. The research worked by Zhao peng which demonstrated the affection caused by angular vibration was worse than which caused by line vibration and what was multiplied direct ratio with plane altitude. So it is necessary to design a new device which could be used widely and has good angular vibration isolation effect. According to the theory of parallelogram the non-angular vibration device had been designed with spatial links and the theory of non-angular vibration was analyzed. The three-dimensional model was set with UG the analysis was done by ADAMS/vibration software. The acceleration and displacement response of the device in each direction was calculated by inspiriting it with sine wave of the acceleration in three directions and the stiffness and damp were studied. All the work prove the design principle of the device is reasonable and the device is adopted to keep the platform motion moving horizontally at the meantime the device is good at isolating vibration in all directions. 2010 SPIE.
