The invention provides a non-contact measurement device for measuring the temperature of the main mirror surface of a large-diameter solar telescope, comprising a main mirror panel (1), an air nozzle (2), an ambient temperature sensor (3), and an air jet temperature sensor (4), a total radiation sensor (5), an anemometer (6) and a data processing module (7). During the working process of the solar telescope, the temperature rise of the primary mirror surface will cause the mirror seeing effect and the thermal deformation of the mirror surface, which greatly limits the performance of the telescope. The device can monitor the temperature of the primary mirror surface in real time, providing an important basis for the temperature control of the primary mirror surface of the solar telescope; at the same time, it also provides data for the analysis of mirror seeing effect and thermal deformation. Compared with the traditional contact temperature measurement device, the device can effectively avoid the damage to the mirror coating caused by the traditional device and the measurement error caused by the temperature sensor being exposed to solar radiation. In addition, the device has the advantages of simple structure, convenient operation, low cost, and strong practicability and innovation.
Description
technical field [0001] The invention relates to the field of solar telescope temperature control, in particular to a non-contact measuring device for measuring the temperature of the primary mirror of a large-aperture solar telescope. Background technique [0002] With the development of modern heliophysics research, the requirements for spatial, temporal and spectral resolutions required for the observation of solar surface activities have been continuously improved, and the aperture of solar telescopes has been continuously increased. At present, the study of solar physics has penetrated into the high-resolution observation of the fine structure of the solar surface, requiring the spatial resolution of the solar surface to reach 50-70km, which requires that the aperture of the corresponding solar telescope must reach 1m or larger. [0003] Due to the difficulty in manufacturing large-aperture sealed windows and the pressure birefringence effect, the traditional vacuum-type...
