Abstract: A control device includes: an acquisition unit that acquires, for an intensity image obtained by observing an action caused by light corrected using a spatial light modulator based on a Zernike coefficient, an intensity distribution that is a distribution of intensities in a plurality of regions of interest within a predetermined range on the intensity image; a generation unit that calculates a comparison result between the intensity distribution and a target distribution to generate comparison data; and a prediction unit that predicts a Zernike coefficient, which is for performing aberration correction related to the light so that the intensity distribution approaches the target distribution, by inputting the comparison data and the Zernike coefficient, which is a basis of the intensity distribution, to a learning model.

Abstract: A microparticle trapping device includes: a fluid channel configured to be injected with a fluid including a microparticle; first and second electrodes configured to generate an electric field in the fluid channel; and an electrical insulator formed with at least one opening between the first and second electrodes in the fluid channel. The electrical insulator is disposed between the first and second electrodes so that an inhomogeneous electric field is made through the at least one opening between the first and second electrodes in the fluid channel, and the still other aspect is configured to trap the microparticle through dielectrophoresis.

Abstract: A control device includes: an acquisition unit that acquires an intensity distribution along a predetermined direction for an intensity image obtained by observing an action caused by light corrected using a spatial light modulator based on a Zernike coefficient; a generation unit that calculates a comparison result between the intensity distribution and a target distribution to generate comparison data; and a prediction unit that predicts a Zernike coefficient, which is for performing aberration correction related to the light so that the intensity distribution approaches the target distribution, by inputting the comparison data and the Zernike coefficient, which is a basis of the intensity distribution, to a learning model.
