Abstract

A color measuring apparatus by using an optical fiber and a small equator is disclosed. In the color measuring apparatus, light from a light source(1) is irradiated to a measuring sample through an optical fiber bundle(3) and is transmitted to a equator(4) so that a reflected light is multi-reflected in the equator(4). An inside of the equator(4) is coated by a material having a high reflexibility. Some illuminance of a surface of equator(4) which is multi-reflected and leveled in the equator(4) is again transmitted to a spectroscope(2) via optical fiber bundle(3).

본 발명은 광섬유와 소형적분구를 이용한 색채측정기에 관한 것으로, 더 상세하게는 광원에서 나오는 빛을 광섬유다발을 이용하여 측정시료에 조사한 후 적분구를 이용하여 반사광을 적분구 내에서 다중반사를 하도록 하며 적분구의 내부는 반사율이 높은 물질로 도포를 함으로써 다중반사하여 평준화된 적분구면의 일부조도를 다시 광섬유 다발로 유도하여 분광장치로 분광한 후 어레이디텍터로 파장별 강도를 측정하고 이 값들을 컴퓨터로 읽어와서 색채계산을 위한 소프트웨어로 색채를 계산하여 화면이나 프린터로 출력하게 한 것이다. 종래에는 광원과 시료, 센서 등의 배열이 렌즈나 거울을 이용하여 고정되어 있었기 때문에 물체색(반사색)만을 측정하기 위한 구조로 되어 있어 용도와 적용성이 한계가 있었다. 본 발명은 이와 같은 종래의결점을 제거코져 분광부의 입력과정에도 광섬유다발을 사용하여 광원색까지 손쉽게 측정할 수 있으며 광원과 적분구의 연결에도 광섬유를 사용하여 적분구 뿐만 아니라 투과색을 위한 보조장치나, 45/0도 측정방식의 보조장치에도 쉽게 착탈할 수가 있기 때문에 용도와 적용성이 넓게 확장시킨 것이다. 이하 발명의 용지를 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.The present invention relates to a color measuring instrument using an optical fiber and a small integrating sphere, and more specifically, to irradiate the measurement sample using a bundle of optical fibers to the measurement sample and to reflect the reflected light in the integrating sphere using the integrating sphere. The inside of the integrating sphere is coated with a material with high reflectance to guide the partial illumination of the integrating integrating sphere into the bundle of optical fibers again, and then spectroscopy with a spectrometer and measure the intensity of each wavelength with an array detector. This software reads the color calculation software and calculates the colors and outputs them to the screen or printer. Conventionally, since the arrangement of the light source, the sample, the sensor, and the like has been fixed by using a lens or a mirror, it has a structure for measuring only the object color (reflected color), which has limited use and applicability. The present invention can easily measure the light source color by using the optical fiber bundle in the input process of the spectroscope to remove such a conventional defect, and the auxiliary device for the transmission color as well as the integrating sphere by using the optical fiber to connect the light source and the integrating sphere. In addition, it can be easily attached to or detached from a 45/0 degree measuring system, thus expanding its use and applicability. Hereinafter, the paper of the present invention will be described in detail with reference to the accompanying drawings.

광원 (1)에서 나오는 빛을 광섬유다발 (3)을 경우 측정시료에 조사한 후 적분구 (4)에 연결하여 반사광을 적분구 내에서 다중반사를 하도록 하되 적분구(4)의 내부는 반사율이 높은 물질로 도포하며 적분구(4)에서 다중반사하여 평준화된 적분구면의 일부 조도를 다시 광성유다발(3)을 경유 분광장치(2)로 연결함과 동시에 45도/0도 측정방식의 보조장치 (5)를 병열 연결함으로써 분광한 후 어레이디텍터로 파장별 강도를측정하고 이 값들을 컴퓨터(6)로 읽어 와서 색채계산을 위한 소프트웨어로 색채를 계산하여 화면이나 프린터로 출력하게 하는 구성이다.In the case of the optical fiber bundle (3), the light emitted from the light source (1) is irradiated to the measurement sample and then connected to the integrating sphere (4) so that the reflected light is multi-reflected in the integrating sphere, but the inside of the integrating sphere (4) has high reflectance. Auxiliary device with 45 degree / 0 degree measurement method, which is coated with material and multi-reflected from the integrating sphere (4), connects some roughness of the integrating sphere surface to the photoluminescent bundle (3) with the diesel spectroscopy device (2) Spectral is connected by parallel connection (5), and then the intensity of each wavelength is measured by the array detector, and these values are read into the computer (6), and the color is calculated by software for color calculation and output to the screen or printer.

이와 같이 된 본 발명은 분광부의 입력과정에도 광섬유다발을 사용하여 광원색까지 손쉽게 측정할 수 있고 광원과 적분구의 연결에도 광섬유를 사용하며 적분구 뿐만 아니라 투과색을 위한 보조장치나, 45도/0도 측정방식의 보조장치에도 쉽게 착탈할 수가 있기 때문에 본 용도와 적용성이 폭넓게 확장된 것으로서 각종 물질의 색채를 효율적으로 측정할 수 있는 것이다.Thus, the present invention can easily measure the light source color using the optical fiber bundle in the input process of the spectroscopic part, and the optical fiber is also used for the connection of the light source and the integrating sphere, and the auxiliary device for the transmission color as well as the integrating sphere, or 45 degrees / 0. Since it can be easily attached to or detached from an auxiliary measuring device, the use and applicability of the present invention are widely extended, and the color of various materials can be efficiently measured.
