Paper Abstract

It is very important for testing of temperature field in laser processing. A new CCD camera based on DSP for measurement of temperature field in laser molten pool is presented in this paper. It uses a DSP as the main CPU without the computer to process images. In this way, the system is simple and efficient. It can not only display 2D morphology and gradient images of temperature field, but also give numerical distribution of temperature field. Comparing with PC-based system, DSP-based system has a small and integrated size, measuring temperature in real time and quickly processing images. After further developing, the system based on DSP could be an useful device in laser processing.
