Abstract
The invention provides a controlling method for light illumination. The method comprises the following steps of firstly obtaining illumination conditions and secondly of setting light focusing conditions. With regard to obtaining illumination conditions, obtain an incident pattern from a laser beam to a spatial light modulator and take the first index of refraction (n1) of a first transmission medium located on the transmission path of the laser beam from the spatial light modulator to a light focusing point and the second index of refraction (n2) of a second transmission medium, different from the first index of refraction (n1), located much closer to a side position of the light focusing point than the first transmission medium as illumination conditions. With regard to setting light focusing conditions, set the numbers (st) of focusing points of a laser beam from a spatial light modulator in a light focusing illumination manner and take the light focusing positions (s number) of the focusing points (st number) and the light focusing intensity as light focusing conditions wherein st is an integral number above one.
