The present invention includes a prism having a light incidence surface and a film formation surface, a metal film disposed on the film formation surface, and a trapping body secured to the metal film. Excitation light is irradiated from an excitation light irradiation part onto an analysis chip installed in a chip holder, and excitation light reflected by the analysis chip is detected. The information outputted by the excitation light irradiation part is acquired.

An image acquisition system includes a feeding unit supplying a product, a product pickup platform onto which the product is supplied by the feeding unit, and a camera capturing an image of the product on the product pickup platform. The camera identifies a position and an angle of the product based on the image. The image acquisition system includes a robot gripping the product from the product pickup platform based on the position and the angle identified by the camera and an image acquisition platform onto which the product is placed by the robot. An imaging microscope of the image acquisition system captures an image of a surface of the product facing upwards on the image acquisition platform and a computer stores the image of the surface of the product captured by the imaging microscope.

Measurement equipment can be used for control with spectroscopic analysis of individual moving objects. The measurement equipment includes a probe with a surface, from which one or more illumination optical fibres and measurement optical fibres emerge. The optical fibres are arranged so that at least one of the second acceptance cones intersects at least one first acceptance cone at less than 10 mm from the surface. The measurement equipment includes a triggering device detecting the objects upstream of the probe to activate or deactivate the observation of the objects by the probe.

Disclosed herein is a method for dynamic analysis of parcels, particularly intended to be implemented within logistics facilities. The method achieves real time analysis of stability performance of the parcels before the parcels enter specific paths within the logistics facility, so that the paths can be chosen based of stability performance of the parcels determined through the method.

An LIBS-type object sorting device includes a three-dimensional-shape measurement means that acquires a space-coordinate group of a top face of an object to be sorted in top view on a conveyor, an LIBS analyzing means that performs chemical composition analysis on the object to be sorted while irradiating the object to be sorted with laser light, and a conveying-path switching means that switches a conveying path of the object to be sorted, in this order. The device includes a computing means that determines an analyzing section on which the LIBS analysis is to be performed, and a control means that causes a beam position to move and causes, when detecting that the analyzing section has reached from a movement amount of the conveyor, based on the movement amount, a beam-focus position to move along the analyzing section while irradiating the laser light.

Provided is a position detection method and a position detection device for detecting a position of a sensor chip and obtaining relative positional information between a well member and a prism as for a well chip type sensor chip in which the well member is provided on a prism. By applying measurement light to the sensor chip while changing a distance between the sensor chip and a measurement light irradiation unit and detecting reflected light traveling in a predetermined direction out of the reflected light generated when the measurement light is reflected by the sensor chip, at least any one of the position of the sensor chip and the relative position between a dielectric member and a sample solution holding member is detected on the basis of a change in intensity of the detected reflected light.

A measurement system used in conjunction with a conveyor includes a first sensor with a first transceiver and a second sensor with a second transceiver. The transceivers transmit a first light beam and a second light beam towards a movable portion of the conveyor. A control unit communicably coupled to the first sensor and the second sensor, wherein the control unit calculates a first distance between the first sensor and the movable portion based on the first sensor and a second distance between the second sensor and the movable portion based on the second sensor. The control unit determines a difference value between the first distance and the second distance; and stops the unloader in response to the difference value being above a predefined threshold value.

A method of synchronizing a line scan camera. The method comprises: obtaining line scan data of a region of interest (ROI) of a travelling surface from the line scan camera, the line scan camera being oriented perpendicular to a direction of travel of the travelling surface, the line scan data comprising a plurality of lines; identifying occurrences of a major frequency of a repeated texture on the travelling surface using characterized line scan data for each line in the plurality of lines of the line scan data; determining a period of the major frequency; and changing a line rate of the line scan camera when the determined period is different than a reference period.

A reagent analyzer and method is described. In the method, a reagent card having a reagent pad is passed through an optical signal path between an optical signal source and an optical signal detector. A transition between a first electrical signal and a second electrical signal is detected to determine a substantially exact position of a leading end or a trailing end of the reagent pad. The first electrical signal is indicative of the substrate interfering with the optical signal. The second electrical signal is indicative of the substrate and reagent pad of the reagent card interfering with the optical signal. The reagent pad is moved to a known second location upon determining the substantially exact position of at least one of the leading end and the trailing end of the reagent pad. At the second location a sample is dispensed onto the reagent pad by a sample dispenser.

A light irradiation angle is set with respect to a first surface so as to detect only either first reflected light or second reflected light. Then, light is emitted from a light irradiation part at the set irradiation angle while a detection chip is kept in motion, either the first reflected light or the second reflected light is detected by a reflected light detection part, and positional information of the detection chip is acquired on the basis of the result of the detection of the first or second reflected light. The detection chip is moved, on the basis of the acquired positional information, to a detection position where detection of a substance to be detected is performed. While the detection chip is kept at the detection position, detection of the substance to be detected is performed through detection of sample light.
