Abstract: A system and method for estimating a concentration of monoethanolamine (MEA) in a fluid. A substrate for supporting a sample of the fluid during testing includes a carbon nanotube mat layer, a silver nanowire layer disposed on the carbon nanotube mat layer, and a chemical enhancer layer disposed on the silver nanowire layer. A sample of the fluid is placed on the substrate, and the fluid sample is radiated with electromagnetic radiation at a selected energy level. A detector measures a Raman spectrum emitted from the sample in response to the electromagnetic radiation. A processor estimates the concentration of MEA in the sample from the Raman spectrum and adds a corrosion inhibitor to the fluid in an amount based on the estimated concentration of MEA to reduce the concentration of MEA in the fluid.

Abstract: A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 7 and a photodetector 4 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 4b is disposed between light detecting portions 4a, 9a, while a reflection unit 6 is provided so as to oppose a region R in a light-absorbing substrate 2, whereby the size can be kept from becoming larger. Ambient light La is absorbed by the region R in the substrate 2. Any part of the light La transmitted through the region R in the substrate 2 is reflected to the region R by the unit 6 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.

Abstract: A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.

Abstract: Systems for measuring optical properties of a specimen are disclosed. The systems are configured to sample signals related to the measurement of the properties of a specimen, and perform software-based coherent detection of the signals to generate resulting measurements are based on the signals acquired at substantially the same time instance. This facilitates the displaying or generating of the desired measurements in real time. In one configuration, the system is configured to direct a modulated light signal at a selected wavelength incident upon a specimen. In another configuration, the system is configured to direct a combined light signal, derived from a plurality of light signals at different wavelengths and modulated with different frequencies, incident upon a specimen. In yet another configuration, the system is configured to direct a plurality of light signals modulated with different frequencies incident upon different regions of a specimen.

Abstract: Methods and systems are provided, which pattern an illumination of a metrology target with respect to spectral ranges and/or polarizations, illuminate a metrology target by the patterned illumination, and measure radiation scattered from the target by directing, at a pupil plane, selected pupil plane pixels from a to respective single detector(s) by applying a collection pattern to the pupil plane pixels. Single detector measurements (compressive sensing) has increased light sensitivity which is utilized to pattern the illumination and further enhance the information content of detected scattered radiation with respect to predefined metrology parameters.

Abstract: A compact transducer system includes both an antenna subsystem and an optical transducer subsystem. The antenna subsystem may include multiple radio frequency (RF) radiating elements disposed adjacent to a ground plane. The ground plane may also serve as an optical reflector within an optical path of the optical transducer subsystem. A secondary reflector may also be provided within the optical path of the optical transducer subsystem. The secondary reflector may be formed of dielectric material (e.g., meta-material) in some embodiments to prevent undesired coupling with RF circuitry.
