The invention relates to measuring equipment and can be used in a fiber-optic thermometer for measuring human body temperature of the internal environment. Declared sensor optical fiber thermometer for measuring human body temperature of the internal environment, filled with the thermometric substance as a clear cycloaliphatic epoxy brand «ERL 4221". According to this utility model, thermometric substance located in the cavity vacated by the end of the optical fiber core. By the end wall of the cavity end of the optical fiber released from the core is attached reflective plate by applying a thin layer of non-toxic transparent adhesive on the end wall of the end of the optical fiber. Non-toxic transparent adhesive is used to protect the reflective plate from mechanical deformations, from the aggressive chemical environment inside a human body. A reflective plate is used to reflect the optical radiation entering the cavity is released from the core end of the optical fiber to guide the optical radiation back into the core of an optical fiber and further to the photodetector. The outer surface of the sensor optical fiber thermometer is nontoxic black light-absorbing coating for increasing the ability of the sensor to the absorption of heat of radiation of biological sites internal environment of the human body in order to reduce the thermal time constant of heating the sensor element a fiber-optic thermometer and, accordingly, increase the speed of optical fiber thermometer on the basis of the proposed sensor. The technical result - an increase of speed fiber optic thermometer on the basis of the present sensor, security measure human body temperature of the internal environment with a fiber optic thermometer. 1 ZP f ly-1-yl.Полезная модель относится к измерительной технике и может быть использована в волоконно-оптических термометрах для измерения температуры внутренней среды организма человека.
