    摘要： Methods and apparatus for article authentication include an exciting radiation generator that exposes an area of the article to exciting radiation, and at least two radiation detectors that detect emitted radiation from the area in a first band and in a second band that does not overlap the first band. The first band corresponds with a first emission sub-band of an emitting ion, and the second band corresponds with a second emission sub-band of the same emitting ion. A processing system calculates a comparison value that represents a mathematical relationship (e.g., a ratio) between a first intensity of the emitted radiation in the first band with a second intensity of the emitted radiation in the second band, and determines whether the comparison value compares favorably with an authentication parameter. When the comparison value compares favorably with the authentication parameter, the article is identified as being authentic.

    摘要： A method and a device for image producing measurement of fluorescent light, according to which a sample containing fluorophores of different species is irradiated with excitation light of at least one excitation channel defined by its spectral properties. The fluorescent light emitted by the sample is received by at least one detection channel defined by its spectral detection characteristic, and is converted into a digital signal, which is stored for further processing The properties of a number of measuring channels, respectively defined as specific combinations consisting of an excitation channel and a detection channel, are automatically set before conducting the measurement according to the result of a mathematical optimization process, which takes into account the fluorescence characteristics of at least some of the fluorophores presumed by the user to be in the sampler.

    摘要： A system for laser scanning provides spectral flexibility needed for the spectroscopic monitoring of highly multiplexed samples, such as cellular and particle assays in whole blood or other suspensions. In accordance with embodiments of the present invention, the system comprises a scanner to direct an excitation laser through a sample, an objective to collect light emitted by the sample in response to the excitation laser, a spectrograph to disperse the emitted light over a plurality of wavelengths as a spectrum, and a charge coupled device for detecting the spectrum. The system can be used with samples having a variety of reporter tags, including one or more SERS tags, fluorescent organic and protein tags, and quantum dot tags. A laser scanning apparatus and method of using the same is also provided.

    摘要： A system and method for metered dosage illumination in a bioanalysis or other system includes an illumination system or subsystem that can provide optimized amounts of excitation light within the short exposure times necessary to measure fast biological activity. The amount of light can be precisely measured to provide quantitative results. The light flux can be precisely controlled to generate a prescribed minimum amount of light, in order to reduce adverse lighting effects on both fluors and samples. The system and method is particularly useful in any quality-control, analysis, or assessment-based environment. Typical research and development applications can include quality control, instrument calibration, and light output standardization; while clinical and diagnostics applications can include clinical monitoring, bioassay calibration and control for diagnostics, treatment and or therapeutic evaluation.
