摘要: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

摘要: A system and method for self-calibrating optical turbidity measurements includes a housing comprising a cavity with an inner wall having an essentially straight section and an opening for the medium. An optical standard is moveable between first and second sections within the essentially straight section, and a light source and a light sensor, arranged at the first section and configured to measure the turbidity of the medium, when the optical standard is at the second section, and configured to measure the turbidity of the optical standard and to determine, as a function of the measured turbidity, a calibration coefficient for performing a self-calibration, when the optical standard is at the first section.

摘要: A method of calibrating an optical sensor may include acquiring a first characteristic for an external light source through a detector of an optical sensor while an internal light source of the optical sensor is turned off; driving the internal light source; acquiring a second characteristic for the internal light source and the external light source through the detector, based on driving the internal light source; and acquiring a reference characteristic of the internal light source, for calculation of an absorbance of an object, based on the first characteristic and the second characteristic.

摘要: Metrology targets, design files, and design and production methods thereof are provided. The targets comprise two or more parallel periodic structures at respective layers, wherein a predetermined offset is introduced between the periodic structures, for example, opposite offsets at different parts of a target. Quality metrics are designed to estimate the unintentional overlay from measurements of a same metrology parameter by two or more alternative measurement algorithms. Target parameters are configured to enable both imaging and scatterometry measurements and enhance the metrology measurements by the use of both methods on the same targets. Imaging and scatterometry target parts may share elements or have common element dimensions. Imaging and scatterometry target parts may be combined into a single target area or may be integrated into a hybrid target using a specified geometric arrangement.

摘要: Provided herein are an optical test platform and corresponding method of manufacturing the same. The test platform may include a shell defining a cavity for receiving a sample tube, a first aperture, and a second aperture. The first aperture and the second aperture of the shell may each be configured to optically couple the cavity with an exterior of the shell. The test platform may further include a first window and a second window embedded in the shell. The first window may seal a first aperture and the second window may seal a second aperture. The first window and second window may each permit the optical coupling of the cavity with the exterior of the shell. The first window and the second window may be optically coupled via the cavity, and the shell may prohibit optical coupling between the first window and the second window through the shell.

摘要: This invention discloses a Reverse Intensity Correction method for spectral library search to correct for instrument response without the side effect of magnifying the noise in the low responsivity region of test spectra. Instead of applying relative intensity correction to the sample test spectra to match the standardized library spectra, a reverse intensity correction is applied to the standardized library spectra to match the uncorrected sample spectrum. This simple procedural change improves library search performance, especially for dispersive CCD Raman analyzers using NIR excitations, where the instrument response often varies greatly across the spectral range, and SNR in the low responsivity regions is typically poor.
