With the increase of experimental projects with microtomography and the limited
beamtime allocated for users, the time for tomographic data collection becomes the main factor
affecting the efficiency of microtomography. An automated sampling robot and a sample calibrate
system based on machine vision are developed to improve the efficiency of data collecting for
microtomography. The control system, detector system and data storage system have also been
optimized to improve the efficiency of microtomography.
