Abstract
A micro object control apparatus for controlling motion of a micro object within a medium includes a light source, an optical vortex generation unit, an objective lens, an imaging unit, an analysis unit, and a movement unit. The analysis unit acquires first motion information of the micro object based on the image data in which the micro object optically trapped with the optical vortex is imaged by setting the focal position of the optical vortex to a first position, acquires second motion information of the micro object based on the image data in which the micro object optically trapped with the optical vortex is imaged by setting the focal position of the optical vortex to a second position, and evaluates a state of an optical trap of the micro object with the optical vortex by comparing the first motion information and the second motion information.
