Title:
ROTARY THREE-DIMENSIONAL LIGHT EXCITATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/284702
Kind Code:
A1
Abstract:
A rotary three-dimensional light excitation apparatus, comprising: a rotating base (1), a periscope group, a light modulating apparatus (2) and a sample container (3). The periscope group is mounted on the rotating base (1), a light beam of the light modulating apparatus (2) enters the periscope group along a central rotation axis of the rotating base (1), the periscope group offsets the light beam of the light modulating apparatus (2) to a position intersecting with the central rotation axis of the rotating base (1), the point of intersection being within the sample container (3); after a light beam is modulated by the light modulating apparatus (2), it is offset by the periscope group on the rotating base (1) and, under rotation of the rotating base (1), can illuminate a sample introduced into the sample container (3) from different angles; and light beams of different angles and different shapes are superimposed to excite a specific three-dimensional shape in a three-dimensional space, thereby improving efficiency of three-dimensional light excitation, and the sample container (3) does not need to be moved, which facilitates replacement.
