The utility model relates to a kind of infrared radiation temperature measurement device device, exactly is a kind of high speed infrared Radiation Temperature Measurement Instrument.
Existing infrared radiation temperature measurement device device is highly suitable for the temperature survey of the tested surface of those non-contact types.But this temperature measuring device can only be measured the operating mode of tested surface temperature constant, and its time response is general all on the order of magnitude of second and millisecond.Tested surface temperature to tested device under those complex working conditions, the quick change procedure of microsecond in full, particularly at tested surface because of suffering under the situations such as bombardment, sputter, ablation or plated film, when radiance changes in the extremely short time, the temperature survey of the tested surface when this temperature measuring device can not adapt to the fast temperature variation.
It is a kind of under the complex working condition condition that the purpose of this utility model is to provide, and can reflect the fast-changing high speed infrared Radiation Temperature Measurement Instrument of tested surface temperature of tested device fast.
Technical solution of the present utility model is: a kind of high speed infrared Radiation Temperature Measurement Instrument, comprise bracing frame, can divide optical fiber, lens, optical filter, detector and amplifier, it is characterized in that: the described input end of optical fiber that divides is fixed on the bracing frame, the built-in lens of its input end, can divide optical fiber to be divided into two bundles through the bundle knot, be divided into the indirect optical filter that wavelength is different of output terminal difference of the divided optical fiber of two bundles, optical filter is indirect with detector respectively, and detector is connected with amplifier respectively.
Below in conjunction with drawings and Examples the utility model is illustrated.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model user mode synoptic diagram.
As seen from Figure 1, bracing frame 1 is formed by glass plate 1-1 and back up pad 1-2 bonding.After can dividing optical fiber 2 beam splitting on demand, its input end is fixed on by back up pad 1-2 on the side of glass plate 1-1, and the built-in lens 3 of its input end are to improve the sensitivity of temperature measurer.Can divide optical fiber 2 to be divided into two bundles, be divided into the different optical filter 4-1 and the 4-2 of the output terminal indirect wavelength of difference of the divided optical fiber 2 of two bundles through bundle knot 2-1.The wavelength of optical filter 4-1 and 4-2 is the narrow band pass filter in the 1-6 micrometer range, and its bandwidth is the 0.1-0.5 micron, and transmittance is greater than 65%.Greater than 50%, the splitting ratio that can divide optical fiber 2 was near 1: 1 in the wavelength coverage of 1-6 micron for the transmittance that can divide optical fiber 2.
Optical filter 4-1 and 4-2 are indirect with detector 5-1 and 5-2 respectively, and it is femaleization of the high speed infrared indium diode with very fast time response of nanometer that detector 5-1 and 5-2 select the response time for use, and it can measure the variable quantity of temperature in the microsecond magnitude.Selecting the optical filter 4-1 and the 4-2 of two kinds of different wave lengths for use, be transferred to two detector 5-1 and 5-2 respectively, is the signal that received in order to ensure two detectors 5-1 and the 5-2 same point from the space.
Detector 5-1 is connected with 6-2 with amplifier 6-1 respectively with 5-2, and the signal that detector 5-1 and 5-2 are received is amplified to suitable numerical value and through after calculating, can obtains the temperature value of being surveyed through amplifier 6-1 and 6-2.The response frequency of amplifier 6-1 and 6-2 makes the time resolution of this temperature measurer reach 1 microsecond at 1MHZ.
During use, only the bracing frame 1 of this temperature measurer need be fixed on and get final product (referring to Fig. 2) on the tested device 7.
The utility model is owing to adopt double-colored measuring principle, the radiation that is about to measured surface space point is behind lens light gathering, pass to and to divide optical fiber, pass to two detectors respectively after the optical filter filtering of two kinds of different wave lengths of fiber-optic output again through being divided into two bundles, to guarantee the same point of two signals that detector was received from the space, signal through amplifier be amplified to suitable numerical value and as calculated after, can obtain the temperature value of the measured surface of the device of surveying; Simultaneously, because detector is selected infrared femaleization indium diode and the radio-frequency amplifier that is exceedingly fast time response for use, thereby make the temporal resolution of this temperature measurer reach 1 microsecond.Through experimental calibration, this temperature measurer gained measured result is: the measurement range of temperature is 100-1500 degree centigrade, and thermometric error is less than 1%, and spatial resolution is 10 millimeters, and temporal resolution is 1 microsecond; And it is simple in structure, the three-dimensional space-time that can measure the tested device temperature under any exceedingly odious condition distributes, can provide high-temperature plasma centesimal temperature variation of first wall temperature when broken wall especially, for the quick variation and the energy deposition process of wall temperature under all kinds of extreme conditions in scientific research and the commercial production provides strong temperature measuring device.
