Abstract
Improved image quality by structured illumination or pivoting illumination and faster image acquisition are both achieved. A line light enters first to fifth virtual pixels of a grating light valve, and first to fifth lights are emitted respectively from the first to fifth virtual pixels. The intensities and phases of the first to fifth 0th-order lights respectively depend on the arrangements of sub-pixels included in the first to fifth virtual pixels. The first to n-th 0th-order lights are extracted respectively from the first to n-th lights, and the first to n-th 0th-order lights are converted respectively into first to fifth light sheets. The first to fifth light sheets are created at a portion to be illuminated. The arrangements of the sub-pixels included in the first to fifth pixels are controlled such that a structured light sheet or pivoting light sheet is created at the portion to be illuminated.
