在金刚石砧式超高压装置中,测温用的光学高温计的使用和一般使用情况不同。它要通过显微镜的光学系统去进行测量。因此,必须经过标定。在用红宝石荧光法测量压力时,存在着杂光干扰的问题。本文介绍一种标定光学高温计的方法和讨论在杂光干扰区如何估计压力。 In the diamond anvil-type ultra-high pressure device, the use of optical pyrometers for temperature measurement and the general use of different conditions. It goes through the microscope’s optical system to make the measurement. Therefore, it must be calibrated. There is a problem of stray light interference when measuring pressure with the ruby ​​fluorescence method. This article describes a method of calibrating an optical pyrometer and discusses how to estimate pressure in a stray light disturbing area.
