摘要： A system for inspecting a coating on a substrate, the system including a platform that receives a sample including the substrate having the coating, and a light source that directs a plurality of electromagnetic pulses towards a scanning location on the coating, wherein the light source is oriented to direct the plurality of electromagnetic pulses at an oblique angle relative to a surface of the coating. A light detector receives electromagnetic pulses reflected from the sample, wherein a first portion of each electromagnetic pulse is reflected from the surface of the coating, and a second portion of each electromagnetic pulse is reflected from a surface of the substrate. An actuator is coupled to the platform and/or the light source, wherein the actuator moves the platform and the light source relative to each other such that the plurality of electromagnetic pulses are directable towards the scanning location from different rotational positions.

摘要： A method of estimating relative change of the 3D position of an object (e.g., sample drift in a microscopy system) having fiduciary markers that have an asymmetric joint point spread function distribution includes generating a plurality of calibration curves for each of the markers during a calibration phase including first calibration curves for a PSF width and second calibration curves for lateral bias. The method further includes capturing a first image of the markers during a data acquisition phase, generating a first joint 3D position for the markers using the first image, the first calibration curves and the second calibration curves, capturing a second image of the markers during the data acquisition phase, generating a second joint 3D position for the markers using the second image and the first and second calibration curves, and estimating the sample drift using the first joint 3D position and the second joint 3D position.

摘要： The present disclosure relates to a system and method for automatic online monitoring of dimethyl sulfide in environment. The method may realize separation of water vapor and the substance to be detected in accordance with the adsorption phase equilibrium principle of substance, thus eliminating the influence of water vapor on detection. The disturbance of other substances in an environmental sample can be eliminated in accordance with the charge or proton transfer principle of molecule ion reaction. Automatic online sampling, preprocessing and sample injection units are configured using valves, numerically controlled motor-driven injectors, flow controllers and a peristaltic pump, so that continuous online detection of DMS in an environmental water sample (e.g., seawater, or lake water) or a gas sample (e.g., atmosphere) can be realized.

摘要： A sample handling device for a laboratory automation system comprising a first carousel with a disc supported on a first axis, a second carousel with a disc supported on a second axis parallel to the first axis, and a transfer element between the first and second carousels is presented. Each disc has recesses distributed radially about the disc perimeter. Each recess receives a tube carrier. The first carousel and the second carousel connect via a passage for transferring sample tube carriers between the first and second carousels. The transfer element is a track switch which when in a rest position partly closes the passage to separate the first carousel from the second carousel. The track switch is swiveled and/or rotated about a third axis parallel to the first axis out of the rest position for transferring a tube carrier from the first carousel to the second carousel via the passage.
