Provided is a fluid analysis apparatus and a method of controlling the same. The fluid analysis apparatus include an actuator provided on a part of the fluid analysis apparatus, a mounting portion on which a fluid accommodating cartridge is mounted thereon, the fluid accommodating cartridge provided with a well in which a fluid sample is accommodated, a measurement portion configured to transmit light to the fluid accommodating cartridge and detect an optical signal from the light passed through the fluid accommodating cartridge, and a controller configured to control an operation of the actuator based on the optical signal detected by the measurement portion such that the light transmitted from the measurement portion passes through a central portion of the well to perform an accurate inspection on the fluid sample.

The invention relates to a device and method for determining a property of a sample that is to be used in a charged particle microscope. The sample comprises a specimen embedded within a matrix layer. The device comprises a light source arranged for directing a beam of light towards said sample, and a detector arranged for detecting light emitted from said sample in response to said beam of light being incident on said sample. Finally, the device comprises a controller that is connected to said detector and arranged for determining a property of said matrix layer based on signals received by said detector.

An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.

Disclosed are systems and methods for performing a contamination estimation of a downhole sample comprising at least a formation fluid and/or a filtrate. A plurality of downhole signals are obtained from the downhole sample and one or more of the signals are conditioned. At least two of the conditioned signals or downhole signals are fused into a multivariate dataset. From optical and density properties of the formation fluid and/or of the filtrate, a multivariate calculation is performed to generate concentration profiles of the formation fluid and the filtrate.

A method for inspecting a pillar-shaped honeycomb structure includes steps of: capturing a pattern of reflected light from an end face with a camera and generating an image data of the pattern of the reflected light; distinguishing positional information of each of cells adjacent to an outer peripheral side wall and cells that are not adjacent to the outer peripheral side wall based on the image data of the pattern of the reflected light, and storing the distinguished positional information in a memory; capturing a pattern of transmitted light from the end face with the camera and generating an image data of the pattern of the transmitted light; measuring intensity of each transmitted light from the cells adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information; and measuring intensity of each transmitted light from the cells that are not adjacent to the outer peripheral side wall to detect the cells having defective plugged portions that are not adjacent to the outer peripheral side wall based on the generated image data of the pattern of the transmitted light and the positional information.
