    摘要: The present invention generally relates to systems and methods for acquiring multiple spectra from a sample, for example, a microfluidic sample. In some aspects of the invention, spectra from a series of locations within a sample are recorded and analyzed, and optionally correlated with an image of the sample. The spectra can be obtained by passing a plurality of light beams through a sample, e.g., using an array of microlenses, diffracting the light beams passing through the sample with a transmission grating, before or after passing the light through the sample, and detecting the resulting light, e.g., as an image. The light beams may pass through the sample before or after passing through the transmission grating. The image can appear as an array of discrete spectra, where each spectrum is associated with a region of the sample where a light beam passed through the sample. The spectra can be analyzed to determine information about the region where the light beam passed through the sample. In some cases, the array of microlenses may be movable and/or replaceable with a second array of microlenses. Also, in some instances, the transmission grating may be movable and/or replaceable with a second transmission grating.

Various antenna designs are considered depending on the laser under consideration and applications. This invention has wide ranging applications such as new microscopes for high-resolution spatially resolved imaging and spectroscopy, new probes for biology, laser assisted processing and repair of devices, circuits and masks, as well new optical tweezers and phased array devices.

    摘要: A system and method for quantifying opaque inhomogeneities within a fluid sample. The system uses an optical lens system (10, 200) to focus a light beam (13, 100) onto a stage (14, 104) where the sample (120) is introduced. The light beam (13, 100) is directed onto the sample in a pattern such that the intensity of transmitted light is measured as a function of path length. A photo detector (16) measures the transmitted light through the sample. Fluctuations in transmitted light intensity are then correlated with detection of opaque inclusions in the sample. The system also includes an automated program which utilizes these optical concentration measurements to determine the fouling potential of visbroken tars and optionally the peptization value (PV), and regulates the introduction of chemical inhibitors into a visbreaker unit to improve the yield or quality of light streams and/ or the economic value of product.

    摘要: A method and apparatus for performing refractive index, birefringence and optical activity measurements of a material such as a solid, liquid, gas or thin film is disclosed. The method and apparatus can also be used to measure the properties of a reflecting surface. The disclosed apparatus has an optical ring-resonator in the form of a fiber-loop resonator, or a race-track resonator, or any waveguide-ring or other structure with a closed optical path that constitutes a cavity. A sample is introduced into the optical path of the resonator such that the light in the resonator is transmitted through the sample and relative and/or absolute shifts of the resonance frequencies or changes of the characteristics of the transmission spectrum are observed. A change in the transfer characteristics of the resonant ring, such as a shift of the resonance frequency, is related to a sample's refractive index (refractive indices) and/or change thereof. In the case of birefringence measurements, rings that have modes with two (quasi)-orthogonal (linear or circular) polarization states are used to observe the relative shifts of the resonance frequencies. A reflecting surface may be introduced in a ring resonator. The reflecting surface can be raster-scanned for the purpose of height-profiling surface features. A surface plasmon resonance may be excited and phase changes of resonant light due to binding of analytes to the reflecting surface can be determined in the frequency domain.

    摘要: System and method for fluorescent light detection from biological samples to enhance the numerical aperture and/or reduce the cross-talk of the fluorescent light. The numerical aperture is enhanced by changing the material of construction of a numeral aperture (NA) enhancing element, such as a truncated sphere, in the fluorescent light detection system, such that NA enhancing optial element (40) is constructed of a different material than the housing (560) containing the sample. To eliminate the spherical aberration, the housing is positioned in a source plane that is offset from the theoretical aplanatic source plane. Cross-talk is reduced by using a mask (440).
