Abstract: The present invention provides an inspection device that is capable of detecting foreign matter with high accuracy, the inspection device including: a light source; an electro-optic element on which light from the light source is incident and which changes a phase of the light into at least two states; and a controller. The controller corrects a phase fluctuation of the electro-optic element itself, using intensity modulation characteristics of the eletro-optic element which are obtained by changing an applied voltage that is input to the electro-optic element.

Abstract: An imaging flow cytometry apparatus and method which allows registering multiple locations across a cell, and/or across multiple flow channels, in parallel using radio-frequency-tagged emission (FIRE) coupled with a parallel optical detection scheme toward increasing analysis throughput. An optical source is modulated by multiple RF frequencies to produce an optical interrogation beam having a spatially distributed beat frequency. This beam is directed to one or more focused streams of cells whose responsive fluorescence, in different frequencies, is registered in parallel by an optical detector.

Abstract: To improve the detection sensitivity, detection accuracy, and reproducibility when electrostatic discharge is generated in a sample solution and analysis is performed using light emission in the generated plasma. A flow channel 100, which has cylindrical main portions each expanding conically from a narrow portion, is filled with a conductive sample solution, and an electric field is applied to the flow channel 100 to generate plasma in the generated air bubbles, so that the resulting light emission is measured.
