Abstract:
PURPOSE: An illuminating optical system, a light radiation device for measuring a spectrum, and a spectrum measurement device thereof are provided to control the occurrence of interference fringe. CONSTITUTION: An illuminating optical system (100) comprises a laser diode (11), a collimator lens (13), a pitching element (10), an integrator lens (15), and a condensing lens (17). The pitching element changes an incidence angle of a laser ray by collecting the laser ray emitted from the laser diode in the integrator lens. The condensing lens collects light emitted from the pitching element. The integrator element comprises a first integrator element and a second integrator element. The second integrator element receives the laser ray radiated from the first integrator element.
Abstract:
PURPOSE: Remote absorption spectroscopy by encoded electrical transmission is provided to measure a medium or components in the air by neglecting a scattering return of a partial route and to reduce a transmission power loss. CONSTITUTION: Remote absorption spectroscopy by encoded electrical transmission comprises a generator, a transmitter(110), and at least one receiver(130). The generator generates multispectral electromagnetic radiation waves with spectral contents in accord with an absorption band and an off-line band of a medium. The transmitter defines a relation of one or more spectral components inside the off-line band and one or more spectral components inside the absorption band by changing the generated spectral contents, thereby transmitting the changed radiation waves through the medium. The receiver is arranged at an arbitrary position with respect to the transmitter, thereby receiving the transmitted radiation waves through a line-of-sight propagation via the medium.

Abstract in simplified Chinese:一种接收入射光之光学头,光学头包含穿透式余弦校正组件以及朝向穿透式余弦校正组件配置之反射组件。穿透式余弦校正组件配置于入射光之一光径上,并对反射组件屏蔽入射光。入射光在射入穿透式余弦校正组件后被转换为朗伯场形之一散射光。反射组件具有光学输出区与反光区,其中光学输出区使散射光通过,而反光区反射散射光至穿透式余弦校正组件及/或反光区之其他部分。亦提供一种使用上述光学头之光学系统。
Abstract:
분광(分光)모듈(1)의 제조방법에서는, 광검출소자(5)와 광투과판(56)이 접합되어 구성된 광검출유니트(10)를 광학수지제(63)에 의해서 기판(2)의 전면(前面)(2a)에 접착한다. 이 때, 광검출소자(5)의 광통과구멍(50)이 광투과판(56)에 의해서 덮여져 있기 때문에, 광통과구멍(50) 내로의 광학수지제(63)의 진입이 방지된다. 게다가, 광검출유니트(10)를 준비할 때에는 광검출부(5a)가 마련된 반도체기판(91)과 광투과판(56)을 접합시킨 후에, 반도체기판(91)에 광통과구멍(50)을 형성하기 때문에, 굴절이나 산란 등의 발생의 원인이 될 수 있는 것이 광통과구멍(50) 내로 진입하는 것을 확실히 방지할 수 있다.
