| titleOfInvention | A laser track tracking device and tracking test method based on photothermoelectric effect |
| abstract | A laser track tracking device and method based on photothermoelectric effect belong to the technical field of electronic devices. The tracking device includes a flexible substrate, a thermoelectric film and four electrodes; the thermoelectric film is located on the substrate, the four electrodes are respectively arranged on the four sides of the thermoelectric film, and two adjacent electrodes are not connected to each other. The method includes the steps of position calibration, spot positioning and trajectory tracking. According to the influence of the illumination position in the photo-thermoelectric effect on the output voltage signal, a type of thermoelectric thin film material is used to prepare a laser trajectory tracking device, and the laser trajectory tracking device is prepared by testing the light in two directions. The thermoelectric output voltage signal can realize laser positioning and trajectory tracking in a two-dimensional plane. The invention has the advantages of simple assembly, easy signal measurement and long service life, and can realize the function of laser trajectory tracking based on a small amount of output signals, reduce the amount of calculation, and improve the data processing efficiency, so it has important application value. |
