Abstract
The invention discloses a thermometer based on the photovoltaic characteristic of a high-temperature superconducting material. The technical scheme adopted in the invention is as follows: according to the thermometer based on the photovoltaic characteristic of a high-temperature superconducting material, laser emitted by a laser generator is irradiated on a high-temperature superconducting material which is connected in series with an amplifier circuit through a wire, the amplifier circuit is connected with the input end of a single chip microcomputer, and the output end of the single chip microcomputer is connected with a display screen. The high-temperature superconducting material is a copper-based high-temperature superconducting material (yttrium barium copper oxide or bismuth strontium calcium copper oxide) or an iron-based high-temperature superconducting material. The laser generator can irradiate laser on the high-temperature superconducting material through a quartz material. The biggest characteristic of the thermometer is high speed of response to temperature (less than 3ms). A temperature measuring device and a display device can be separately arranged, which is more advantageous to the test of a low-temperature area. The thermometer of the invention is simple in design structure, sensitive to the ambient temperature, fast in response, and especially suitable for temperature detection in an ultralow-temperature environment.
