Abstract: A test sample for testing a recording fluorometer/densitometer has multiple tracks with features that generate detector outputs indicating performance parameters. In the normal mode of operation the instrument scans the optical absorbance or fluorescence characteristics of electrophoretic samples in a plurality of tracks on a thin agarose film plate. In order to correctly record the optical characteristics of these electrophoretic samples, the instrument must respond linearly and with the correct range, resolution and alignment. A test sample is scanned in the same manner as a normal sample. The resulting instrument output provides easily analyzed information on fluorometric and densitometric performance parameters including linearity, range, spatial resolution, slit and scan path alignments, scan speed and excitation uniformities, response time, noise, electrical and optical offsets, integration accuracies, automatic gain and zeroing accuracies.

The method comprises illuminating the target with the light emitter, detecting light reflected from the target using the light detector, wherein the light detector provides an electrical output signal SS indicative of the intensity of the detected light, and determining the optical reflectance R of the target according to (Formula 1), where RR is the spectral reflectance of a reference standard, SR is the detector electrical output signal with the reference standard in place, SH is the detector electrical output signal with no target in front of the light emitter and light detector, and M is a calibration factor.

Abstract: A method for removing noise from spectral data recorded using a spectrometer. The method includes normalising spectral data to generate normalised spectral data and applying a machine learning model to the normalised spectral data. The machine learning model is trained to remove noise from spectral data using normalised training data, wherein the spectral data is normalised based on a different scaling to the normalisation of the training data.

Abstract: An apparatus for measuring not only the reflected radiation but also the fluorescence emission of a textile sample, which includes a presentation subsystem having a viewing window. A radiation subsystem has a tunable radiation source for directing a desired radiation having a wavelength range and an intensity through the viewing window toward the sample, and thereby causing the sample to produce a fluorescence. A sensing subsystem has an imager for capturing the reflected radiation and fluorescence in an array of pixels. A control subsystem has a processor, for controlling the presentation subsystem, the radiation subsystem, and the sensing subsystem, and creates a reflected radiation and fluorescence image containing both spectral information and spatial information in regard to the reflected radiation and fluorescence #843 of the sample.

Abstract: A method for analysing parameters of fluid in a hose, comprising the steps: calibrating a current of a light source for emitting light so that the signals resulting from light received by a receiver arranged behind an air filled hose and a fluid filled hose allow a differentiation between the signal for an air filled hose and a fluid filled hose; emitting light at a defined wavelength through the hose wherein the receiver is arranged behind the hose with an angle to the light beam axis; detecting a phase boundary between air and fluid during aspiration of the fluid into the hose by measuring signals; determining when the hose is filled with fluid; increasing the current of the light source when the hose is filled with fluid; measuring absorption of the light and scattered light; and evaluating the amount and intensity of the measured absorbed and/or scattered light.

Abstract: Methods and systems for calibrating simulated measurement signals generated by a parametric measurement model are described herein. Regression on real measurement signals is performed using a parametric model. The residual fitting error between the real measurement signals and simulated measurement signals generated by the parametric model characterizes the error of the parametric model at each set of estimated values of the one or more floating parameters. Simulated measurement signals are generated by the parametric model at specified values of the floating parameters. A residual fitting error associated with the simulated measurement signals generated at the specified values of the floating parameters is derived from the residual fitting errors calculated by the regression on the real measurement signals. The simulated measurement signals are calibrated by adding the residual fitting error to the uncalibrated, simulated measurement signals. The calibrated, simulated measurement signals improve the accuracy of measurements and measurement recipe development.
