近年来随着科学技术的发展,新型红外探测器相继问世,如热释电探测器、硅光电池、碲镉汞等。特别是硅光电池具有稳定性好、体积小、结构牢固、成本低廉等优点,它能成功地取代热电堆、光电管等元件,在辐射测温仪中得到了广泛的应用。我们研制的红外辐射测温仪(自动光学高温计)采用硅光电池做接收元件,利用热 In recent years, with the development of science and technology, new infrared detectors have come out one after another, such as pyroelectric detectors, silicon photovoltaic cells, such as mercury cadmium telluride. In particular, silicon photovoltaic cells have the advantages of good stability, small size, firm structure, low cost and the like. They can successfully replace the components of thermopiles and photocell and are widely used in radiation thermometers. We developed the infrared radiation thermometer (automatic optical pyrometer) using silicon photovoltaic cells as the receiving element, the use of heat
