    Abstract: PURPOSE:To enable exact data sampling by inserting a layer of a medium of which the refractive index varies with wavelength to one side of bisected two optical paths more than into the other optical path and making the two optical path asymmetrical. CONSTITUTION:A medium layer of which the refractive index varies slightly with wavelength is inserted into either of optical paths for two light beams (a), (b) asymetrically from the other. A laser light source N emits a visible light beam which is made incident to an interferometer and is detected by a detector D'. As a movable mirror M2 moves, the quantity of the visible light incident to the detector D' fluctuates periodically and therefore the output from the D' is made by waveform shaping into the sampling pulses to operate a sumple holding circuit SH. The pulses are at the same time counted by an arithmetic control circuit C. The start point for scanning of the mirror M2 is taken at the position of suitable -X and the photometric outputs in the positions x1, x2-xn for the count values 1, 2, 3-n of the sampling pulses are stored in a memory Me. The circuit C reads out the data from the memory Me and calculates power spectra after one time of scanning with the mirror M2.

    Abstract: Analytical radiation from a source 10 enters a Michelson-type interferometer including a beam splitter 13 and a movable reflecting member 17. Quadrature phase discrimination is employed to provide signals indicative of the position and direction of movement of a portion of member 17 within the analytical radiation path, using a beam from laser 25 directed onto beam splitter 13 and, after reflection by fixed mirror 15 (via retardation plate 27) and movable mirror 17, passed coaxially with beam 11 to detector 28. Multiple quadrature phase discrimination systems may be employed to indicate of the position and direction of movement of three portions of a flat reflecting member. One portion may be within the analytical radiation path. An initial reference indicative of the position of the movable reflecting member independently of the beam splitter and an additional quadrature phase discrimination system may be provided. The reference system may provide redundantly an indication of position and direction of movement of member 17.

    Abstract: 고해상도 단일 칩 분광계가 기술된다. 본 발명의 실시예는 푸리에 변환 분광기와 유사하지만; 본 발명의 실시예는 어떠한 가동부도 갖지 않는다. 예시적인 실시예는 복수의 네스티드 마하 젠더 간섭계(MZI)를 갖는 분광계로서, 모든 MZI는 그의 샘플 및 기준 암 각각에 있는 적어도 하나의 표면-도파관 부분을 공유한다. 샘플 및 기준 암의 광 신호는 electro-optically-controlled 방향성 커플러를 통해 그들 길이를 따라 일련의 불연속 위치에서 태핑되고, 이들은 각각의 암에 있는 균일한 길이 도파관 부분에 의해 분리되지만, 균일한 길이가 샘플 및 기준 암에서 상이하여 각각의 MZI의 암에 대해서 상이한 경로 길이 차이를 제공한다. 샘플 및 기준 암으로부터의 탭 광은 암의 시간 지연 차의 함수로서 광파워의 분포를 생성하기 위한 저 손실 빔 컴바이너에 재결합된다.
