摘要： An engineered video inspection lighting system includes a three-dimensional array (22) of solid-state light emitting diodes (18) focused to an inspection area. A single high-current, low-duration pulse is applied to selected elements of the array. Light thus generated is passed through a diffuser (26) and to a specimen (D). Light reflected from the specimen is received by a lens (32) of a video camera (34) disposed in an interior of the three-dimensional array (22). Data thus obtained is used to determine acceptability of the specimen in accordance with preselected standards.

摘要： A video inspection system includes first and second video cameras (36 and 48) mounted along a parallel axes. A lighting array (16) is pulsed, and resultant light is reflected from a specimen to both cameras. Orientation of the specimen is determined in accordance with an image generated from a first camera (36). This data is used to isolate a selected portion of the specimen for analysis by an image generated from the second camera (48).

摘要： Systems and methods for driving optical sources operating at different wavelengths within a smoke sensor are described herein. Multiple optical sources such as light emitting diodes may be used in a photoelectric smoke sensor to detect particles of different sizes. Photoelectric smoke sensors can operate by pulsing the LEDs and measuring a response in a light sensor. The signal measured at the light sensor changes based on the quantity of particles existing in a smoke chamber. Each optical source may have different operational characteristics and thus require different drive currents to operate. LED driving circuitry according to embodiments discussed herein provide a consistent and reliable drive current to each optical source, while maximizing efficiency of power consumption across a range of possible voltages provided by different power sources.

摘要： Light emitted from a light casting unit 1 including an LED as its light source is cast into a sample cell 2, and a photodetector 3 is placed at a position where the resultant passing light can be detected. The LED is driven to blink, and a data extracting section 71 extracts data obtained in a period in which the LED is turned on, as data (absorbance data) in which absorption of light by the sample solution is reflected. Moreover, in the case where a fluorescent component is contained in the sample solution, fluorescent light is emitted by the cast light serving as excitation light. Even after the excitation light ceases, the emission of the fluorescent light continues for a short time, and hence the data extracting section 71 extracts data obtained immediately after the LED is turned off, as data (fluorescence data) in which the fluorescent light is reflected. An absorbance computing section 72 calculates absorbance based on the absorbance data, and a fluorescence computing section 73 calculates fluorescence intensity based on the fluorescence data. Accordingly, it is possible to simultaneously perform an absorbance measurement and a fluorescence measurement on one sample while using one photodetector and thus simplifying the configuration of an optical system.

摘要： A device and method for identifying solid and liquid materials use near-infrared transmission spectroscopy combined with multivariate calibration methods for analysis of the spectral data. Near-infrared transmission spectroscopy is employed within either the 700-1100 nm or the 900-1700 nm wavelength range to identify solid or liquid materials and determine whether they match specific known materials. Uses include identifying solid (including powdered) and liquid materials with a fast measurement cycle time of about 2 to 15 seconds and with a method that requires no sample preparation, as well as quantitative analysis to determine the concentration of one or more chemical components in a solid or liquid sample that consists of a mixture of components. A primary application of such analysis includes detection of counterfeit drug tablets, capsules and liquid medications.

摘要： An imaging system with an imaging mechanism which includes polarization analyzers, which may be crossed polarization analyzers, positioned to provide birefringence images of particles in the fluid passing through the flow chamber. Captured images are of high resolution and may be used in comparison to known images of a library of images. The system and related method enhance the accuracy and sensitivity of particle monitoring by utilizing birefringence imaging combined with particle analysis and the detection of each particle's characteristic features, such as crystalline features. The system includes a scatter detector used to trigger backlighting of the flow chamber and capture images of particles therein.
