A computer aided thick pinhole collimating system was developed for X-ray or Gamma ray pin-hole imaging applications. This system consists of two laser theodolites and actuators, a digital video camera, a laptop computer and a specifically developed software package. Functions including aided focu-sing, aided light axis adjustment and parameter recording were implemented. Compared with single light axis method, this system can shorten the collimating adjustment time,and achieve better precision. It can also provide long-term reference axis. Data processing and alignment criterion were discussed.
