Abstract: A method is provided for authenticating a botanical. The method includes identifying at least one marker compound of the botanical. A sample comprising the botanical is injected into a chromatography system that includes a mobile phase delivery module, an autosampler, a chromatography column, a chromatography column manager, and at least one detector. The method also includes extracting a chromatogram of the at least one marker compound and extracting a spectrum at a chromatographic peak retention time of the at least one marker compound. The method also includes quantifying at least one peak of the extracted chromatogram and quantifying at least one band of the extracted spectrum. The quantified at least one peak of the extracted chromatogram and the quantified at least one band of the extracted spectrum are compared to a set of authentication criteria to determine authenticity of the botanical.

Abstract: The present disclosure describes devices and techniques for testing. In particular, the disclosure describes testing systems that are portable and easy to operate. The testing system can include a measurement apparatus that can be used to measure spectral characteristics of a sample and can be in a portable, hand-held form-factor. The testing system also includes a computing device, such as a mobile phone, a laptop, or a personal computer that can communicate with the measurement device over a wired or a wireless communication link and also can have form-factors that are portable. The computing device can run applications or programs that receive spectral data of the sample from the measurement apparatus and can process the received spectral data to determine various properties of the sample. As both the measurement apparatus and the computing device are portable, the measurements can be easily made at site where the fluid is produced.

Abstract: Multiple optical architectures based on photosensitive arrays are disclosed. The optical engines collect five dimensional data from the samples with three dimensional spatial information and temporal and spectral information simultaneously, in parallel from all channels, without optical scanning. The photosensitive arrays and/or last component of illumination system are in contact or close proximity of the sample surface. The application of optical engines to sensitive detection of species of interest in the complex reflecting and scattering matrix with the high concentration of interfering species is described. The optical engines are applicable to noninvasive, mobile monitoring of various species of interest in vivo and in vitro.

Abstract: A laser ablation tomography system includes a specimen stage for supporting a specimen. A specimen axis is defined such that a specimen disposed generally on the axis may be imaged. A laser system is operable to produce a laser sheet in a plane intersecting the specimen axis and generally perpendicular thereto. An imaging system is operable to image the area where the laser sheet intersects the specimen axis.

Abstract: Systems for measuring optical properties of a specimen are disclosed. The systems are configured to sample signals related to the measurement of the properties of a specimen, and perform software-based coherent detection of the signals to generate resulting measurements are based on the signals acquired at substantially the same time instance. This facilitates the displaying or generating of the desired measurements in real time. In one configuration, the system is configured to direct a modulated light signal at a selected wavelength incident upon a specimen. In another configuration, the system is configured to direct a combined light signal, derived from a plurality of light signals at different wavelengths and modulated with different frequencies, incident upon a specimen. In yet another configuration, the system is configured to direct a plurality of light signals modulated with different frequencies incident upon different regions of a specimen.

Abstract: A microlithographic projection exposure apparatus has a measuring device, by which a sequence of measurement values can be generated, and a processing unit for processing the measurement values. The processing unit has a processing chain which includes a plurality of digital signal processors. The first digital signal processor in the processing chain is connected to the measuring device to receive the sequence of measurement values. Each subsequent digital signal processor in the processing chain is connected to a respectively preceding digital signal processor in the processing chain. The digital signal processors are programmed so that each digital signal processor processes only a fraction of the measurement values and generates processing results therefrom, and forwards the remaining fraction of the measurement values to the respective next digital signal processor in the processing chain for processing.

Abstract: A method for capturing hyperspectral images using a regular color camera. In the method, the camera takes multiple images of a scene, with the camera oriented differently for each image. For a camera carried by an aircraft or spacecraft, this allows hyperspectral imaging without the cost or weight of a hyperspectral camera.
