The main principles of laser direct writing (LDW) system for lines on the spherical surface (SS) are discussed. It is pointed out that line profile is determined by the exposure dose distribution
which lies on the light intensity distribution of focus plane and the scanning speed. To improve the quality of line profile on the SS
several key techniques as follows are introduced. Firstly
the unique system configuration
four axes mutually intersecting at the center of the SS
is adopted
which ensures the shape of the focus be maintained circular during the writing period. Secondly
an automatic focus system (AFS) with the function of automatic focus in a certain range is introduced. Thirdly
to guarantee the linear velocity to accord with the exposure character of the photoresist all the time
an efficient arithmetic that controls motors run at appropriate angular velocity in different latitude is developed. Finally
to achieve a stable and well-behaved system so as to compensate the velocity instability resulting from unavoidable errors of mechanical and electronics factor
a powerful programmable multi-axis controller (PMAC) is utilized as the kernel element of the servocontrol system
and the curves of step response and parabolic response achieved by feedforward and PID loop tuning indicate that the location precision and velocity stability have reached a high level. The experimental results of LDW of lines on the SS work piece with a diameter 30 mm and a radius equal to 100 mm are given. The section analysis of the lines on the photoresist by the atomic force microscope (AFM) after exposure and development is performed. The results show that line width is about 3.0 m
and the steep sides of the lines are parallel to each other.

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
optical system
mechanical constructions
DC serve motor control system
array detector
data acquisition system and computer system for controlling and data analysis of LTP-III. The Instrument has advantages of high accuracy
low cost
multifunction and wide application. Length of surface measured of optical element accuracy is 0.04 arcsec.
