红外光纤测温仪光学系统设计原理

DESIGN PRINCIPLES OF OPTICAL SYSTEM OF IR FIBRE THERMOMETER

介绍红外光纤测温仪光学系统的设计原理，指出在测温仪中严格限制红外视场来消除杂散辐射的干扰可使温度测量值不随被测目标距离的改变而变化。

This paper presents the design principles of optical system of IR fibre thermometer.It is pointed out that in the thermometer restricting the viewing field pricisely and eliminating the stray radiation can cause the measurement values of the thermometer not varying with the distance to the measurement object.
