Other AbstractThe utility model relates to a laser forming process for metal powder, especially a temperature field detection device that is used in the laser forming process for metal powder. The said device comprised :1) a turntable connected to a drive unit 2)a plurality of filters arranged in groups, with two filters in each group, and the filters that employs two wavelengths are fixed to the turntable at uniform spacing 3)a positioning control component, which employs a photoelectric sensor to locate the position of the device 4)an image acquisition unit, which comprises a camera and an image acquisition card, wherein, the infrared images acquired by the camera are take as the input signals to the image acquisition card, and the output signals from the image acquisition card is sent to a computer processing unit 5)a drive unit, which comprises a step motor, wherein, the rotating speed of the step motor is determined against the frame rate of the camera in the image acquisition unit wherein, the temperature field detection device is integrally inclined and mounted beside the optical axis of the laser and fixed to the optical axis. The utility model detects the temperature distribution and variation trend during the laser forming process for metal powder in real time, therefore the parameter of the process is performed by real time temperature adjusting.
