    Abstract: 本发明的一般(或广泛、广义)特征是一个光学装置,该装置中有一个光波导,该光波导中有一个倾斜光栅使得至少部分光从导模耦合入一个或多个辐射光束。倾斜光栅辐射出的光被聚焦成中间像平面上预定位置的中间像,中间像的位置取决于光波长以及光所耦合出的导模的有效折射率。本发明可以在中间像平面上放置一个空间光调制器用以控制光束的相位和(或)幅度。更为显著的是,本发明还包含了一个末级聚焦器件用以将从空间光调制器透过的光聚焦成局部区域内的末级像,从而使得光强提高,也就提高了探测的灵敏度,该末级聚焦器件可以是一个透镜。该发明还包含了一个光接收器,该光接收器可以是光纤或光探测器或用以探测末级像的光探测器阵列。

    Abstract: This invention relates to a dispersive holographic spectrometer (12) for analyzing radiation from an infrared source (16). The holographic spectrometer (12) comprises a piezoelectric block (40) having a holographic lens (38) on one face, an array of detectors (36) on another face and a pair of vernier electrodes (32, 34) on opposite faces. Radiation from the source (16) incident upon the holographic lens (38) is dispersed into component wavelengths (44, 46) and directed towards the detector array (36). The holographic lens (38) has a holographic interference pattern recorded on it such that radiation of predetermined wavelength components are dispersed sufficiently enough such that radiation of specific wavelengths falls on different detector elements (48) of the detector array (36). By applying a voltage to the electrodes (32, 38), an electric field is created within the piezoelectric block (40) such that it is either compressed or expanded. This change in the piezoelectric block (40) alters the direction of the radiation from the holographic lens (38) to the detector array (36). Therefore, misalignment of the source (16) with the holographic lens (38) can be compensated for such that piezoelectric adjustment of the block (40) will make the radiation of individual wavelengths fall on the desired detector element (48). Further, radiation from different wavelengths can be directed from one detector element to another. The detector array (36) is self-scanning such that an absorption spectrum can be measured and recorded over a range of frequencies.

    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.
