Abstract: |
The invention is the double-wavelength photoelectric thermodetector based on blackbody radiation, and belongs to the photoelectric testing technology. The invention uses the quartz glass window to realize the immersible thermometric, which is to use the quartz glass window as the illuminant and pass through the lens, the bidirectional optical splitting filter, the narrow band filter sheet ad the photoelectric converter to realize the conveying, collecting and converting of the optical signals. The invention diminishes the influence brought by the changing of the launching ratio of the iron melt and reduces the disturbance to the environment and improves the thermometric precision. |
