摘要： Planar-mirror-based focus-shift systems usable for various microscope systems including confocal microscopes, fluorescent microscopes, etc., as well as 3D “floating image” display devices. The invention provides light-sheet-illumination systems for 3D applications, using high-speed focal-plane adjustment synchronized to the scanning light sheet to quickly capture a 3D representation, which is especially important for live samples that move. 2D images of an object are captured, and the third dimension is obtained by changing the focal plane used for each image. A series of the 2D images are used to obtain a 3D representation, which optionally is a moving 3D representation of a live moving specimen. Some embodiments provide constant magnification by compensating the magnification factor of one optical focus-shift subsystem by an opposing magnification factor of another focus-shift subsystem. Some embodiments provide a display system that uses a stationary display and a focus-shift subsystem to output a 3D “floating image.”

摘要： Provided in the present application is a holographic display system, comprising an on-site holographic display system, a transmissive geometric holographic display system, a geometric holographic display system with folded optical path, and a reflective geometric holographic display system. A display element capable of directly displaying screens provided with depth of field information is used to project a diverging 3D image in the air without the aid of another reference light source. The image is converted by a projection screen of an equivalent negative refractive index flat lens to then obtain an observable 3D image suspended in the air, which reduces costs. At the same time, the 3D image may be displayed in front of or behind the projection screen, the display space is infinite, and in a very small device space, a super large screen and super deep depth of field may also be displayed.
