Abstract:
An optical apparatus with a single-use, disposable fluid flow cartridge and cell and associated optical interface is employed in determining characteristics of a fluid and/or suspended materials or cells contained therein which are introduced into the apparatus. The optical interface communicates electromagnetic radiation from an optical instrument through the fluid within the cell and to an appropriate sensor within the optical instrument. The interaction of the electromagnetic radiation with the fluid is measured by the signal generated by the sensor. Fluid present within the cell may be static or flowing, allowing both discrete sample measurements and monitoring of continuous processes.
Abstract:
In one aspect, the present invention relates to a system evaluating a surgical margin of tumor tissues of a living subject. In one embodiment, the system includes a light source configured to emit a source light; at least one optical probe; a scanner; a spectrometer; and a controller coupled with the scanner and the spectrometer for operably controlling the scanner and the spectrometer. In operation, a working end of the optical probe is positioned proximate to a surface of a specimen of the tumor tissues. A source channel of the optical probe deliver the source light emitted by the light source from the working end to the surface of the specimen, and a plurality of collection channels collect from the working end diffused/reflected light generated from interaction of the source light with the specimen. The spectrometer receives the collected diffused/reflected light to evaluate a margin status of the specimen.
Abstract:
An SPR sensor cell is an SPR sensor cell including an optical waveguide to be brought into contact with a sample. The optical waveguide includes an under clad layer, a core layer provided in the under clad layer such that at least a part thereof is exposed from the under clad layer, and a metal particle layer covering the core layer exposed from the under clad layer to be brought into contact with the sample.
Abstract:
A method of analysis, instrument for analysis and device for use in such an instrument are provided, which perform a number of processes need to reach a useful result in the context of a wide variety of samples. The sequence of those processes being optimised. A device, instrument using the device and method of use are also provided which offer reliable performance of a heating based process, with minimal condensation and/or sample loss issues.
Abstract:
The present invention relates to a spectral domain optical coherence tomography apparatus having an endoscopic small-sized probe, and more particularly, to a technology imaging an external shape or an internal structure of a sample by a non-contact and non-invasive method by applying an optical coherent fiber bundle probe attached with a lens to Michelson interferometer or a Fizeau interferometer.
Abstract:
The present invention regards methods and devices for detecting plaque on a surface in the oral cavity to which a fluorescent agent capable of binding to plaque has been applied, whereby a radiation source emits incident radiation for contacting the surface, reflected light and fluorescent emission resulting from contact of the radiation with the surface is collected by an optical collector and conveyed by an optical pathway in the device, where the optical light signal of the reflected light and fluorescent emission is converted to an electrical signal, and where the electrical signals of the fluorescent emission and the reflected light are then mathematically manipulated to provide a compensated plaque value as a function of the distance from the optical collector and the surface of the oral cavity to which the fluorescent agent has been applied.
Abstract:
Instruments, devices and methods of analysis are provided which fully integrate a significant number of process steps in a continuous operation. Accurate positioning and full contact between components is also provided by the relative movement the designs allow. An effect interface between a low cost disposable cartridge or device and the instrument to process it is also detailed.
Abstract:
The disclosure relates generally to methods and apparatus for using a fiber array spectral translator-based (“FAST”) spectroscopic system for improved imaging, spectral analysis, and interactive probing of a sample. In an embodiment, the confocality of a fiber array spectral translator-based spectroscopic system is improved through the use of structured illumination and/or structured collection of photons. User input may be received and acted upon to allow a user to interactively in real time and/or near real time view and analyze specific regions of the sample.
Abstract:
The disclosure relates to a portable and/or handheld bioagent detector and methodology described herein that is based in part on advanced Raman Chemical Imaging (“RCI”) technology. According to one embodiment of the present disclosure, the detection system may include a fiber array spectral translator (“FAST”) and may also include a probe which may include a complementary metal oxide semiconductor (CMOS) camera. The probe alleviates the need to place the main instrument close to an unconfined release of a potentially hazardous material and facilitates analysis of a sample that is situated in a hard-to-reach location while minimizing contamination of the detector and operator.
