    摘要: This invention describes an apparatus and method for a self adjusting Raman amplifier for fiber optic transmission lines incorporating a line diagnostic mechanism in order to calculate, control and optimize the operating parameters for the amplifier. This need arises because the amplifier gain medium is the transmission line itself and the amplifier properties depend on the optical fiber properties along the first tens of kilometers of the transmission line from the pump. A Line Analyzing Unit, adjacent to the Raman pump unit, operates before the Raman pump is enabled and during operation, and characterizes the transmission line. The Line Analyzing Unit determines and characterizes the types of optical fibers installed along the transmission line and calculates and optimizes the pump or pumps power in order to achieve optimum gain and gain equalization. The Line Analyzing Unit may also determine if there is an optical loss or reflection in the optical fiber that can be destructive when the high power Raman pump is operating.

    摘要: An improved waveguide for an infrared thermometer, comprising a silver halide optical fiber cable of low transmission loss, a high aspect ratio, and a radially decreasing index of refraction. The transmission loss is low enough to enable the cable to be up to ten meters in length, thereby extending beyond the housing of the thermometer and being insertable in confined spaces such as an ear canal. The small cross sectional area and radially decreasing index of refraction of the cable make the field of view of the cable small enough to enable it to resolve targets as small as a portion of the human tympanic membrane, enabling the device to be used to measure the core temperature of humans and other organisms.

    摘要: A method of active radiometric thermometry. The target, whose temperature is to be measured, is heated briefly and locally, preferably by a pulse of laser radiation. The intensity of infrared or visible radiation emitted by the heated portion of the target is measured as a function of time. The temperature of the target is inferred from the shape of the intensity curve of the emitted radiation as a function of time.
