With the development of aerospace remote sensing technology
the ground resolution of remote sensing camera enhances continuously. Since there is relative motion between camera and ground target when taking pictures
the target image recorded in recording media is moved and blurred. In order to enhance the imaging quality and resolution of the camera
the image motion had to be compensated. In order to abate the effect of image motion to image quality of space camera and improve the resolution of the camera
the compensation method of image motion to space camera is researched. First
the reason of producing drift angle and adjustment principle are analyzed in this paper. This paper introduce the composition and transmission principle of image motion compensation mechanism. Second
the system adopts 80C31 as controller of drift angle
and adopts stepping motor for actuators
and adopts absolute photoelectric encoder as the drift Angle measuring element. Then the control mathematical model of the image motion compensation mechanism are deduced
and it achieve the closed-loop control of the drift angle position. At the last
this paper analyses the transmission precision of the mechanism. Through the experiment
we measured the actual precision of the image motion compensation mechanism
and compared with the theoretical analysis. There are two major contributions in this paper. First
the traditional image motion compensation mechanism is big volume and quality heavy. This has not fit for the development trend of space camera miniaturization and lightweight. But if reduce the volume and quality of mechanism
it will bring adverse effects for the precision and stiffness of mechanism. For this problem
This paper designed a image motion compensation that have some advantages such as small size
light weight at the same time
high precision
stiffness and so on. This image motion compensation can be applicable to the small optics cameras with high resolution. Second
the traditional mechanism control need to corrected
fitting and iterative for the control formula of mechanism. Only in this way
we can get the optimal control mathematical model. This paper has high precision of the control formula derived. It can achieve the high precision control without fitting
It also simplify the difficulty of control mathematical model establishment. This paper designed the range of adjusting of image motion compensation mechanism between -5 +5. Based on choosing-5

+4 as the expectation value of the imaginary drift angle
we get ten groups of the fact data in adjusting drift angle measured. The test results show that the precision of the drift angle control system can be achieved in 1. It can meet the system requirements that the precision of the control system is less than 3'
and it can achieve the high-precision image motion compensation. 2011 SPIE.
