Abstract: A probe includes an optical system which irradiates a site of a biological tissue and receives light emitted from the site, and an imaging device. The imaging device is disposed ahead of the optical system closer to the end of the probe. The probe rotates the incident direction of the light and the imaging direction of the imaging device around a rotation axis directed to the longitudinal direction of the probe while fixing an angle between the incident direction and the imaging direction. The optical system receives the light from the site which always falls in the field of view of the imaging device, or brought with a time lag into the field of view of the imaging device as a result of rotation, the light being incident in the direction normal to, or inclined away from the rotation axis.

Abstract: The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward an optical detector. Signals for the detector are compared with reference signals based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.

Abstract: A method of classifying information in an optical analysis system includes obtaining calibration data defining a plurality of data points, each data point representing values for two or more detectors when sampling a material used to construct a multivariate optical element. Based on the calibration data, one or more validation models can be developed to indicate one or more ranges of expected results. Validation data comprising the models can be used to compare data points representing values for two or more detectors when performing a measurement of a material to determine if the data points fall within an expected range. Classification data can be generated based on the comparison and, in some embodiments, one or more indicators, such as a confidence level in a measurement, can be provided.
