Abstract: The present invention provides a measuring device by which, even if a radiation intensity from a light source, a beam size or a beam intensity distribution of the light source changes, an optical characteristic of an optical element to be measured can be measured very precisely. In a measuring device according to the present invention, to this end, light from a light source is diffracted by a diffracting grating to thereby resolve the same into plural light beams, and by using different light beams, the object to be measured is measured and the intensity of incident light from the light source is measured. With this structure, even if the light from the light source changes, the intensity of the light from the light source is specified concurrently, and therefore, the optical characteristic of the object to be measured can be measured very accurately.

Abstract: An apparatus for detecting the homogeneity of a pharmaceutical mixture has a hopper for containing a mixture of two or more pharmaceutical components and that is situated within a production line of preparation of a pharmaceutical dosage form. A spectroscope is mounted to the hopper for measuring spectroscopic characteristics of the mixture, and a processing device that is not physically coupled to the spectroscope analyzes the spectroscopic characteristics of the mixture and derives information regarding the homogeneity of the mixture. The spectroscope wirelessly sends the spectroscopic characteristics to the processing device, which derives information regarding the homogeneity of the mixture. The wireless transmission of the spectroscopic characteristics can be done through infrared radiation or near infrared radiation, and the spectroscopic characteristics can be converted to digital signals prior to being transmitted.

Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The grating or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.

Abstract: The present invention relates to an optical measurement device, comprising first phase grating and second phase grating, a light source, and at least two optical detectors, said first and second gratings being stationary binary gratings on transparent carrier. The first phase grating is arranged to be reproduced on said second phase grating upon illumination with the light source, which reproduction is coherently achieved, so that periods of the image of the first phase grating and the second phase grating are in an integral relationship with respect to one another, and so that the grating lines of the image of one grating and the other grating are parallel. A relative positional displacement between the image of one phase grating on the other phase grating is registered by said at least two optical detectors.

Abstract: A wavelength monitoring system for continuously monitoring the wavelengths of different optical channels transmitted through a wavelength division multiplexed (WDM) fiberoptic system. In one construction, an optical diffraction grating is used to disperse the light being monitored onto a rotating polygon having mirrors on the facets thereof, such that the rotating polygon reflects the light onto a detector located behind a slit. In a second construction, the light is projected onto a rotating, hollow transparent cylinder having a thin film filter deposited on a surface thereof, wherein the thin film filter comprises a Fabry-Perot structure which has a gap which varies as a function of its position on the rim of the cylinder, such that the varying gap allows for a varying transmission wavelength which varies as a function of angular position. A detector is positioned in the interior of the cylinder to detect light passing through the rotating thin film filter.

Abstract: Auto-calibrating spectrometers and methods that measure transmission or reflection versus wavelength of a sample without need for calibration for long periods of time. Reflection and transmission spectrometers along with auto-calibrating methods for use therewith are disclosed. Light is focused onto a sample using a lens or similar optical element that transmits light towards the sample reflects light impinging upon it, and transmits light reflected from the sample. If one monitors the light reflected from the first lens and sample, very useful information is available related to the system response versus time. The present invention monitors the reflected light from the first lens and sample, and corrects for the system changes over time using this reflected light.

Abstract: Tomographic approaches to hyperspectral imaging, such as CTHIS1 (Chromotomographic Hyperspectral Imaging Sensor), can eliminate the need for the slit, filter, or resonant cavity and substantially increase the optical throughput of the system. These systems capture a large fraction of the photon energy from the entire spectral band over the entire frame time. CTHIS uses a rotating direct view prism as the dispersing element, consequently, the extended image must be reconstructed from the blurred measured data. Only radiation from monochromatic sources such as LEDs, LASERs and signals with high spectral definition, such as the flames of chemical reactions, remain un-blurred in passing through the prism. Thus, the position, wavelength, and temporal evolution of LEDs, LASERs and certain flames can be easily identified in a wide field of view with minimal signal processing.

Abstract translation: CTHIS1（Chromotomographic Hyperspectral Imaging Sensor，高光谱成像传感器）可以消除对缝隙，滤波器或谐振腔的需求，并大大增加系统的光通量。 这些系统在整个帧时间内从整个光谱带捕获大部分光子能量。 CTHIS使用旋转直视棱镜作为分散元件，因此，扩展图像必须从模糊的测量数据重建。 来自诸如LED，LASER和具有高光谱清晰度的信号（例如化学反应的火焰）的单色源的辐射在通过棱镜时保持不模糊。 因此，LED，激光器和某些火焰的位置，波长和时间演变可以在宽视野内以最小的信号处理被容易地识别。
