STRUCTURED ILLUMINATION DEVICE, STRUCTURED ILLUMINATION METHOD, AND STRUCTURED ILLUMINATION MICROSCOPE DEVICE

摘要

[Problem] To adjust a wavelength of a sound wave of an audio-optical element with a simple configuration. [Solution] A structured illumination microscope device (10) comprises a structured illumination assembly (11). The structured illumination assembly (11) further comprises a light source (15), a unit audio-optical element (19), an objective lens (26), and a control unit (29). The light source (15) emits light of a prescribed wavelength. The audio-optical element (19) diffracts light and forms an interference pattern upon a specimen face (16a). The optical lens (26) illuminates a specimen (16) with some or all of the light beam which is diffracted with the audio-optical element (19). The control unit (29) controls the audio-optical element (19) such that the pattern pitch of the interference pattern changes according to the wavelength of the light of the light source (15).
