单片机光纤比色测温仪的研制

The Study of Colourimetric Thermometer Using Optical Fibers with Single Chip Computer

根据光纤比色测温原理并采用单片机研制了光纤比色测温仪。讨论了双色波长的选择方法，前置接收电路的设计问题，并提出一种消除系统漂移的有效方法。研制的测温仪性能达到了国外同类产品的水平。

The author has developed a kind of thermometer with single chip computer on the principle of colourimetric temperature measurement using optical fiber, which attains the performance of similar products from abroad. In this paper, the author discusses the election method of two colour wave length, the design question of the receiving circuit, and introduces an effective way to eliminate the system drift.
