摘要：Several specific types of optical sensors capable of measuring temperature,pressure, force, acceleration, radiation and electrical fields, fluid level, vapor pressure,and the like, are disclosed, along with an electro-optical system for detecting the opticalsignal developed by the sensor. One such probe utilizes a convex shaped structureconsisting of an elastomeric material attached to an end of an optical fiber, theelastomeric material being coated with a luminescent material, a combination that iscapable of measuring both temperature and pressure. Such a probe is also specificallyadapted for measuring surface temperature by making a good physical contact with thesurface being measured. Another such probe utilizes a similar structure but of a non-elastomeric material for the purpose of detecting both temperature and either index ofrefraction of vapor pressure changes. Improvements in other existing sensors of a widevariety of physical parameters other than temperature are also described whereintemperature is simultaneously measured for correcting such physical parametermeasurements that are affected by temperature variations.
