본 고안은 현재 활용되고 있는 전자제품인 VDP(Video Disc Player) 및 카메라의 주요 구성 부품으로서 사용되면서 검파기용으로 많이 쓰이는 제조된파장 편광판(Plate)의 성능을 평가점검하기 위한 레이저빔을 이용한 편광판 성능검사장치에 관한 것이다.This invention is used as a major component of VDP (Video Disc Player) and cameras, which are currently being used, and is used for detectors. Wavelength polarizer ( The present invention relates to a polarizer performance inspection apparatus using a laser beam to evaluate and evaluate the performance of a plate).
종래에는 광학부품을 이용한 전자제품이 많이 나오고 있으나 제품을 구성하고 있는 부품인파장 편광판에 대한 성능을 점검하는데 있어서 점검장치의 구성 결함으로 인해 편광판에 대한 조정장치가 없었기 때문에 정밀한 성능점검을 할수 없었던 결점이 있었다.Conventionally, there are many electronic products using optical parts, but the components constituting the product In checking the performance of the wavelength polarizer, there was a defect that the precise performance inspection could not be performed because there was no adjustment device for the polarizer due to a defect in the configuration of the inspection device.
따라서, 본 고안은 이와같은 종래의 결점을 해소키 위해 점검 장치 구성에 점검하고자 하는 소정의 편광판을 고정판을 통해 고정함과 정확한 성능점검에서 요구되는대로 조절할수 있게 하여 제작완료된파장 편광판의 성능을 점검할수 있게된 것으로써 첨부된 도면에 의해 구성및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is to complete the manufacturing process by fixing the predetermined polarizing plate to be checked in the inspection device configuration to solve such a conventional defect through the fixing plate and to adjust as required in the accurate performance check When the performance of the wavelength polarizer can be checked as described in detail the configuration and effect by the accompanying drawings as follows.
하우징(1)에 장착한 레이저 다이오드(2)와 정해진 일정거리 위치에 집광렌즈(3)를 일직선상으로 몸체(4)에 장착하여 레이저 다이오드(2)로 부터 발산된 레이저빔이 집광렌즈(3)의 특성에 의해 통과하면서 평행광이 되도록 하고, 또한 몸체(4)의 후면에는 반사경(5)을 장착함과 반사경(5)과 집광렌즈(3)사이에 일직선상으로 빔스플리터(Beam Splitter)(6)과 반사경판(10)을 설치하며 반사경판(10)에는파장 편광판(8)을 교체하며 고정할수 있는 고정판(9)을 삽입 장착하면서 빔스플리터(6)의 90°방향의 몸체(4)면에는 센서(7)를 장착한 구성을 갖는다.The laser beam emitted from the laser diode 2 is mounted on the body 4 by mounting the light collecting lens 3 in a straight line at a predetermined distance from the laser diode 2 mounted on the housing 1. By passing through the characteristics of the () to be parallel light, and the rear surface of the body (4) is equipped with a reflector (5) and the beam splitter (Beam Splitter) in a straight line between the reflector (5) and the condenser lens (3) (6) and the reflector plate (10) is installed on the reflector plate (10) The sensor 7 is mounted on the surface of the body 4 in the 90 ° direction of the beam splitter 6 while inserting and mounting the fixing plate 9 which can replace and fix the wavelength polarizing plate 8.
이와같이 구성되어진 본 고안의 작용효과를 설명하면 전자제품의 주요 구성 부품의 하나로 제조된파장 편광판(Plate)(8)의 성능을 평가점검하기 위한 것으로써 하우징(1)에 장착되어 몸체(4)에 설치된 레이저 다이오드(2)를 선택하여 장착하는데 이때 레이저 다이오드(2)에서 발산되는 레이저빔의 발산각(15-35°)이 매우 크기 때문에 평행광을 만들지 않고는 사용할수 없기 때문에 선택된 레이저 다이오드(2)의 레이저빔의 발산점 즉, 광웨이스트를 형성하는 점과 평행광을 만들수 있는 집광렌즈(3)의 촛점이 일치토록 레이저 다이오드(2)와 집광렌즈(3)와의 설치거리가 되어야 하는 조건이 필요하게 되는 것으로 선택되는 레이저 다이오드(2)의 발산점에 따라 집광렌즈(3)의 위치 이동이 필요하게 되며 일단 완전 조성 설치된 상태가 되면 레이저 다이오드(2)에서 발산된 레이저빔은 집광렌즈(3)를 통과하면서 평행광으로 위상차 90°를 갖는 P편광과 S편광이 되어 일직선상으로 장착된 빔스플릿터(6)입사 되며 빔스플리터(6)의 특성에 의해 S편광은 반사되고 P 편광만이 통과하여 고정판(9)에 정착되어 반사경판(10)에 삽입 정착되어 있는 제품인파장 편광판(8)에 입사되어 통과하게 되면파장 편광판(8)은 방향에 따라 다른 굴절율을 가지고 있어서 방향에 따라 각각 다른 위상차를 발생시키게 되어 원래 직선 편광된 P편광만이 통과하게 되면 원평광(Circular Polarization)으로 바뀌게 되어서 진행된 원편광은 몸체(4)에 장착된 반사경(5)에 도달하게 되며 이때 반사경(5)은 알루미늄(Al)은 (Ag)금 (Au)등으로 표면을 입히고 여기에 레이저 파장의정도 유전체 보호 박막을 입힌 반사경으로 되어 있기 때문에 박막에 의해 90°의 위상차가 생김으로 해서 반사광이파장 편광판(8)에 재투과되어 원편광은 S편광으로 바뀌게 되어 빔스프릿터(6)에 의해 광경로가 90°로 꺽여 몸체(4)에 장착된 쎈서(7)로 입사 되는 것으로 레이저 다이오드(2)에는 APC(Automatic Power Control)회로와 전압계및 전류계를 별도로 연결하고 센서(7)에는 눈금으로 파워를 측정할 수 있는 계기를 별도 연결하여 센서(7)에 도달된 광의 파워를 측정하는 것이다.In this way, the effect of the present invention is constructed as one of the major components of electronic products Wavelength polarizer ( Plate (8) for evaluating and evaluating the performance of the laser diode (2) mounted on the housing (1) and installed in the body (4) is selected and mounted at this time, the divergence of the laser beam emitted from the laser diode (2) Since the angle (15-35 °) is so large that it cannot be used without making parallel light, the diverging point of the laser beam of the selected laser diode 2, that is, the point forming the optical waste and the condensing lens that can make parallel light ( The position of the condenser lens 3 is shifted in accordance with the divergence point of the laser diode 2 which is selected to require a condition that the distance between the laser diode 2 and the condenser lens 3 is to be set so that the focal point of 3) matches. Once the complete composition is installed, the laser beam emitted from the laser diode 2 passes through the condenser lens 3 and becomes P-polarized light and S-polarized light having a phase difference of 90 ° as parallel light. The mounting beam splitter (6) is incident and which is manufactured by fixing into the S polarized light is reflected and the P polarized light passes through only the fixing plate 9 is fixed on the reflector plate 10 by means of the characteristics of the beam splitter 6 When incident and passed through the wavelength polarizing plate 8 The wavelength polarizer 8 has different refractive indices according to directions, and thus generates different phase shifts according to directions. When only the linearly polarized P polarized light passes, the polarized polarizer 8 changes to circular polarization. 4) the reflector 5 is mounted, and the reflector 5 is coated with aluminum (Ag), gold (Au), etc. Because it is a reflector coated with a dielectric protective thin film, a 90 ° retardation is caused by the thin film, so that reflected light The circularly polarized light is retransmitted to the wavelength polarizing plate 8 so as to be converted into S-polarized light, and the light path is bent by the beam splitter 6 at 90 ° to be incident on the sensor 7 mounted on the body 4. 2) to connect the APC (Automatic Power Control) circuit and the voltmeter and ammeter separately and to the sensor 7 is connected to the instrument that can measure the power by the scale separately to measure the power of the light reached to the sensor (7).
이때파장 편광판(8)을 고정판(9)으로 부터 분리 교체해 가면서 계속적인 성능을 점검하게 되는데 고정판(9)을 통해파장 편광판(8)의 각도를 조절하여 집광렌즈(3)를 통과한 광이 반사경(5)에 의해 반사한후 반사전 경로와 같아지도록 세팅하여 센서(7)에 도달된 최저의 파워 차이로써 성능을 정밀하게 점검하게 되는 것으로써 전자제품에 부품으로 사용되는 정밀 광학부품인파장 편광판(8)을 본 고안의 성능 점검장치를 이용하므로써 정밀한 성능 점검으로 널리 사용되는 광학부품의 성능을 체크하게 됨에 따라 광학 산업 발전에 크게 기여하게 되는 것이다.At this time By separating and replacing the wavelength polarizer 8 from the fixed plate 9, the continuous performance is checked. Adjust the angle of the wavelength polarizing plate 8 so that the light passing through the condenser lens 3 is reflected by the reflector 5 and then set to be the same as the pre-reflection path, thereby performing performance as the lowest power difference reached by the sensor 7. Is a precision optical component that is used as a component in electronic products. By using the wavelength polarizing plate 8 to check the performance of the optical component widely used in the precise performance check by using the performance check device of the present invention will contribute greatly to the development of the optical industry.
