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.
