研究了一种利用激光干涉原理进行非接触式测温的方法,该方法能在不破坏样品表面的前提下,准确、方便、廉价地获取玻璃在真空中的真实温度。在相关实验中以Pilkington TEC系列钠钙玻璃为样品,在150~500℃之间同时对样品进行热电偶测温和激光干涉测温,实验数据表明,非接触式激光测温方法得到的温度数据与热电偶直接接触样品表面测得的温度数据在误差10℃范围内基本相同。证明了这种非接触式的方法可用于以玻璃为基底的太阳能电池生产领域。
A method of non-contact temperature measurement based on laser interferometry is studied. The method can accurately, conveniently and cheaply obtain the true temperature of glass in vacuum without destroying the sample surface. In the related experiment, Pilkington TEC series soda-lime glass is taken as a sample, and the temperature of the sample is measured by a thermocouple and a laser interferometer at a temperature between 150 and 500 ° C. The experimental data show that the temperature data obtained by the non-contact laser temperature measuring method The temperature data measured in direct contact with the thermocouple on the sample surface is approximately the same within an error of 10 ° C. This non-contact method proved to be useful in the production of glass-based solar cells.
