The present invention involves new, innovative optical fiber probes, applied for temperature measurement with a quick response time. This new type of probe is composed of an IR wave-guide, including the following: a wave-limiter; a wave-splitter, an exponent/logarithm transfer, a logarithmic subtractive device, a self-adjustable wave-cutting device, and an opto-electric probe head. The probe quickly responds to temperature, 1 ms or less, then releases the data captured digitally. This invention, offering numerous possible widespread applications, could replace thermocouples and sensors utilized for contact and non-contact measurement, as well as become an ideal for standard temperature measurement. The dual-waves optical method and the digital technique of the optics are both applied to this invention. Based on the above-mentioned, multi-functional fiber optical sensors, capable of measuring a variety of biological, chemical, and physical quantities, can be developed.
The present invention relates to a fiber optical probe for the high-speed measurement of temperature. A main feature of the probe is the infrared wave-guide, composed of the wave-limiter, the wave-splitter, exponent/logarithm transfer, and the logarithm subtractive device. The infrared light wave emitted from the heat source is selectively divided into two sequent waves by the waveguide. The dual-waves are compared and divided by the exponent/logarithm transfer and the logarithm subtractive device;
