The precision of FOG has highly effect on the servo system's final precision. In this paper
two filter methods has been researched in signal processing of FOG
smoothing filter method and Kalman filter based on ARMA model
in order to improve turn table servo control system's performance. To validate the effects of these two methods
three experiments have been made
which are filter examinations
dynamic experiments and Static experiments. The experiments reveal that these two kinds of filter methods are useful to filter the unknown noises and very effective to improve the precision of servo control system. 2010 IEEE.

The trace of star trail is an important component of deep sky detection. The stars are low contrast targets
and their self-rotation will make their brightness change in cycle. Above all
the trail trace is vulnerable to the block and disturbance of other stars. Traditional one-dimensional maximum entropy thresholding algorithm is vulnerable to the noise
and the calculation of two-dimensional entropy methods is too large and takes too much time. This paper proposes an improved two-dimensional entropy threshold algorithm. We use recursion iteration method to eliminate the redundancy calculation
and reduce the size of two-dimensional histogram based on the deep sky stars characteristic
such as low contrast
fuzziness and the centralized histogram. We also combine our algorithm with the space trail trace model to forecast the star trace. Experiments results show
when the star are blocked or they turn dark
the method still can well extrapolate the star trace. Our method improves the capability of trailing the ebb and small star
and increases the precision of tracing. It is also robust to the noise
so there is a good application foreground for the method.

Metallic mesh has been widely used in electromagnetic interference windows. While the duty ratio of curved mesh equals to planar mesh'
the theory of planar mesh may be applied to curved mesh according to equivalent-circuit model. So the idea that latitude lines intersect latitude lines to form isometric mesh on the concave of a sphere is put forward
and the method of fabricating the mesh by concentric optical scan is introduced. The movement parts of equipment consist of an erection turning
a horizontal dividing and a pitching dividing spindle. Firstly
a spherical substrate is fixed on the horizontal dividing spindle that has been set horizontally on the erect turning spindle
the substrate revolves around the axis of the erect spindle
the tube of object lens that is fixed on the pitching dividing spindle steps at pitching direction
and a revolving circuit of the substrate corresponds to a step of the tube. Gradually
a set of latitude lines is attained. Afterward
the substrate makes a quarter turn around the horizontal spindle
another orientation latitude lines are also gained. Thus
the isometric mesh on the concave of a spherical substrate is gained. The process comprises surface cleaning
coating photoresist
laser direct writing
development
evaporated film
dissolving photoresist and plating. The fabricated spherical mesh has a line width of 7 m and a period of 600m. Experiment shows that infrared transmission and electromagnetism shield efficiency of the metallic mesh are relatively consistent with theoretical value.
