Abstract:
이 분광 모듈에서는, 회절층(6) 보다도 두꺼워지도록 회절층(6)의 둘레(6a)를 따라서 칼라(collar)부(7)가 일체로 형성되고 있고, 게다가, 렌즈부(3)의 곡면(3a)에서 칼라부(7)와 접촉하는 부분이 조면으로 이루어져 있다. 이것에 의해, 곡면(3a)과의 접착성이 높아진 칼라부(7)에 의해서, 회절층(6)이 포위되게 된다. 이 때문에, 회절층(6)을 박형화해도, 회절층(6)이 렌즈부(3)의 볼록한 모양의 곡면(3a)으로부터 박리하는 것을 방지할 수 있다. 또한, 이 분광 모듈에서는, 칼라부(7)에서 렌즈부(3)의 곡면(3a)과 대향하는 후면(7a)이 평탄면으로 이루어져 있다. 이것에 의해, 광이 칼라부(7) 내로 입사해도, 그 광은 칼라부(7)의 평탄면인 후면(7a)에 도달한다. 이 때문에, 미광으로서 광 검출 소자의 광 검출부에 직접 결상되는 광을 저감할 수 있다.

A calculator(140) is received the electric signal transformed with detector. The temperature is calculated.
Abstract:
A wavelength tunable spectrometer and a wavelength tuning method thereof are provided to secure optimum diffraction efficiency according to a wavelength of incident light, to maintain an optical path for observation, to increase a degree of freedom in a design thereof, and to reduce a volume thereof. A transmissive diffraction unit(105) is rotatably arranged in an optimum incident angle according to external incident light in order to diffract the incident light. A mirror(103) is arranged in a fixed angle to the transmissive diffraction unit in order to reflect the diffracted light in the same angle as the incident angle to the transmissive diffraction unit, to a predetermined optical path. A driving unit(113) rotates the transmissive diffraction unit and the mirror in an angle according to the wavelength of the incident light. A light collection unit collects an optical output applied through the mirror. An observation unit observes a spectrum of the light collected through the light-collecting portion.
Abstract:
A method for detecting disease in a patient includes providing infrared (IR) light and coupling the IR light through direct lens coupling or through a first group of one or more optical fibers. IR light is reflected from a portion of the patient and collected by a lens arrangement or a second group of one or more optical fibers. The reflected IR light is dispersed into its spectrum which is detected and analyzed. An apparatus suitable for diagnosing a disease in a patient includes an IR light source and optical fiber or direct lens coupling of IR light onto a body part or fluid of the patient. Reflected light from the patient is optically dispersed using a prism or grating. An IR focal plane array receives the optically dispersed light. The spectrum of the reflected IR light is used to provide a diagnosis of disease in the patient by identifying various disease markers or chemical fingerprints. The method and apparatus are capable of non-invasively detecting disease markers in a patient.

The device includes: an image formation optical system (10); a branching optical system (12) for branching an image light flux obtained by the image formation optical system into a plurality of light fluxes and again forming an image by the branched light fluxes on the division image formation surfaces (30a, 30b); and a camera unit (14) including a single-plate color imaging element (16) having an image formation position on the division image formation surfaces. ® KIPO & WIPO 2007
Abstract:
An apparatus and method are provided. In particular, at least one first electro-magnetic radiation may be provided to a sample and at least one second electro-magnetic radiation can be provided to a non-reflective reference. A frequency of the first and/or second radiations varies over time. An interference is detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. Alternatively, the first electro-magnetic radiation and/or second electro- magnetic radiation have a spectrum which changes over time. The spectrum may contain multiple frequencies at a particular time. In addition, it is possible to detect the interference signal between the third radiation and the fourth radiation in a first polarization state. Further, it may be preferable to detect a further interference signal between the third and fourth radiations in a second polarization state which is different from the first polarization state. The first and/or second electro- magnetic radiations may have a spectrum whose mean frequency changes substantially continuously over time at a tuning speed that is greater than 100 Tera Hertz per millisecond.
