In addition, a Peltier element is used to enable the surface of the blackbody to have a large diameter of 50 mm or more and then be applicable to an FTIR hyperspectral spectrometer which requires a reference light source having a large diameter for calibrating IR signals.

Description

FTIR 초분광 분석장치의 복사 보정용 평판형 적외선 흑체{Plane Type IR Blackbody for Radiometric Calibration of a FTIR Hyperspectral Spectrometer}(Plane Type IR Blackbody for Radiometric Calibration of a FTIR Hyperspectral Spectrometer)

본 발명은 초점면 배열 검출기(Focal Plane Array)를 사용하는 FTIR 초분광 분석장치인 경우에 복사 보정을 위해 사용 가능한 평판형 적외선 흑체에 관한 것으로서, 보다 상세하게는 검출기의 픽셀별로 균일한 복사 보정용 광원을 제공하고, 표면적을 넓혀 복사 휘도를 높인 피라미드 구조의 표면을 갖는 평판형 적외선 흑체에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat infrared ray black body usable for radiation correction in the case of an FTIR ultrasonic spectroscopic analyzer using a focal plane array, And has a surface of a pyramid structure having an increased surface area and an increased radiance.

FTIR(Fourier Transform Infrared Spectroscopy) 기반 초분광 분석장치에서 획득된 분광신호에는 측정된 배경 신호 외에 적외선 광선을 분광하는 과정에서 장치 내의 검출기, 투과창, 간섭계 등 광학부품 특성에 의해 생기는 신호가 포함되어 있다.The spectroscopic signals obtained by the FTIR (Fourier Transform Infrared Spectroscopy) -based spectroscopic analyzer include signals generated by characteristics of optical components such as a detector, a transmission window, and an interferometer in the apparatus in the process of spectroscopying the infrared ray in addition to the measured background signal .

이때 기준이 되는 이상적인 광원인 흑체에 대한 적외선 분광 응답율을 측정하여 보정 계수를 얻고, 임의의 적외선 신호를 보정해야 정확한 스펙트럼 신호처리가 가능하다.At this time, the infrared spectral response rate of the black body, which is a reference light source, is measured to obtain a correction coefficient, and an arbitrary infrared signal must be corrected to enable accurate spectral signal processing.

현재 국내에서 FTIR 분광장치의 분광신호 보정용으로 사용되는 흑체는 캐비티형 구조이다. 캐비티형 구조의 흑체는 TTRS 적외선 소자에서 점광원 형태로 방사되는 흑체광선을 콜리메이션(Collimation)하여 출력되도록 구성한 것으로 전력소모가 작고, 야외 환경성에 우수한 장점이 있지만 시준 광학계를 사용함으로써 투과 손실이 발생하여 복사 방출율이 떨어지게 되고, 복사 휘도의 균일성이 떨어지는 단점이 있어 초점면 배열 검출기를 사용하는 FTIR 초분광 분석장치에 적용시 각 픽셀에 해당되는 영역에 신뢰성 있는 복사 스펙트럼 제공이 어렵다.At present, the black body used for the spectral signal correction of the FTIR spectroscope in Korea is a cavity type structure. The black body of the cavity type structure is configured to output the black body light emitted from the TTRS infrared device as a point light source in the form of collimation, which is advantageous in terms of power consumption and outdoor environment. However, transmission loss is caused by using a collimated optical system Therefore, it is difficult to provide a reliable radiation spectrum in a region corresponding to each pixel when applied to an FTIR ultrasonic spectroscopic analyzer using a focal plane array detector, because the radiation emission rate is lowered and the uniformity of the radiation luminance is lowered.
