Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight
and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem
the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target
the angular velocity of visual axis in inertial space is zero
so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation
the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally
some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.

The imaging quality of seeker in flight mode has been evaluated through analyzing the effects of missile flutter on optical modulation transfer function (MTF) of the optical system. Firstly the data of transverse vibration has been processed to eliminate the trend term caused by the trajectory
then obtained the displacement with two times trapezoidal integration. For the side rotation
the high frequency noise interference in the data has been filtered by using five-point moving average method. Took this model as the quivering rule between the object and the image
and then analyzed the effects of the transverse vibration and the side rotation on imaging quality through MTF. By calculation
the r.m.s value of the image motion caused by missile transverse vibration is 0.026mm
and the side rotation angle is 0.0044 . Through the establishment of two modulation transfer functions (MTF) of image random vibration and linear vibration
the results show that the image quality had declined
and the effect of transverse vibration on image quality is obvious. Through improving the rigidity of the missile and selection of small focal length optical system and shorten the time of exposure can improve the imaging quality of the seeker. 2010 IEEE.

The phase changing rates1 of laser beam in single mode polarization maintaining fiber (PMF)
Yb-doped rectangular inner cladding dual-clad fiber (DCF) and Yb-doped large-mode-area dual-clad fiber (LMF) are investigated by means of interference under situations with different exterior disturbance
for situations that all the fibers are used as transmission medium only
as well as amplifying medium with the last two. In this paper
phase fluctuation characteristics of the beam transmitted through the fibers with no amplification are presented. The results show that the phase fluctuation frequencies of the laser beam transmitted through these three kinds of fibers are mainly in the range of 100-200Hz
100-300Hz and 80-400Hz respectively in normal laboratory environment. The phase fluctuation frequencies of the laser beam transmitted through the DCF
in cases of when the environment temperature is changing
a constant pressure is applied to the fiber and when vibration is applied
are mainly in the range of 100-600Hz
100Hz-300Hz and 100-500Hz respectively. In the same cases
for the LMF
the phase fluctuation frequencies are mainly in the range of 150-600Hz
100-400Hz and 100-1000Hz
respectively. It indicates that for realizing phase stabilization
the bandwidth of any potential phase control2 system has to be in the range of a few kilohertz.
