摘要： A detection system for a multilayer film is provided. The detection system for a multilayer film includes a light source device, a first image capture device, a second image capture device and an image processing device. The light source device projects a pair of parallel incident light to a transparent multilayer film obliquely. The pair of parallel incident light is projected onto the transparent multilayer film for producing and enabling a forward scattered light and a back scattered light to be projected therefrom. The first image capture device captures the back scattered light to produce a first image. The second image capture device captures the forward scattered light to produce a second image. The image processing device is coupled to the first image capture device and the second image capture device. The image processing device is used to compares and detect the differences between the second image and the first image.

摘要： An apparatus comprises a detector, a pressure sensor and a processor. The detector is operable to detect light that is scattered by an aerosol that is associated with a pressure. The pressure sensor is operable to measure the pressure. The processor is coupled to the detector and to the pressure sensor, and is configured to receive at least a signal from the detector and the pressure sensor. The processor is further configured to use the received signals to calculate a volume of the first aerosol, and to output an output signal associated with the calculated volume. The various measurements can be repeated and compared, and the output signal can be a feedback signal for metering subsequent amounts of the aerosol, based on the comparison.

摘要： Microfluidic methods and systems for detecting levels of microorganisms via Mie forward light scattering. The systems and methods of the present invention can be customized so as to optionally maximize scatter from the particle immunoagglutination and minimize that of the sample matrix, e.g., via selection of parameters particle diameter d, wavelength of incident λ, and/or scatter angle θ. Methods feature providing beads conjugated with an antibody specific for the microorganism, mixing beads with a sample to form a first mixture; providing a control mixture; irradiating the mixtures with incident light; detecting forward light scattering scattered by the first mixture at a first angle with respect to the incident light and forward scattered light scattered by the control the same first angle with respect to the incident light; determining I and I0 from the light scattering; comparing I with I0; and determining a level of the microorganism.

摘要： An in-line holographic microscope is used for measurements of micrometer-scale particles and associated suspending fluid medium containing the particles. The system yields heterodyne scattering patterns that may be interpreted with Lorenz-Mie theory to obtain precise time-resolved information on the refractive index of the suspending medium for determining chemical composition, concentrations and makeup thereof. This approach can perform spatially resolved refractometry with measurements on calibrated refractive index standards and monitor chemical concentration in a microfluidic channel. Using commercially available colloidal spheres as probe particles and a standard video camera for detection yields volumetric refractive index measurements with a resolution of 2×10−3 RIU for each probe particle in each holographic snapshot.
