A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-infrared light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.

A stereoscopic image display apparatus that is capable of being efficiently aligned using a remotely controlled alignment function and a method of displaying a stereoscopic image using the same are disclosed. The stereoscopic image display apparatus includes a polarizing beam splitter for spatially splitting image light emitted by a projector into at least one transmitted beam and at least one reflected beam based on polarized components, at least one modulator for adjusting the transmitted beam and the reflected beam such that the transmitted beam and the reflected beam have different polarization directions when a left image and a right image are projected by the transmitted beam and the reflected beam, an angle adjustment unit for adjusting the position on a screen on which the transmitted beam is projected in response to a first remote control signal, a remote-control alignment type reflecting member for adjusting the path of the reflected beam in response to a second remote control signal such that the reflected beam overlaps the transmitted beam projected on the position on the screen adjusted in response to the first remote control signal in order to form a single image, and a remote controller remotely connected to the angle adjustment unit and the remote-control alignment type reflecting member for transmitting the first remote control signal and the second remote control signal to the angle adjustment unit and the remote-control alignment type reflecting member, respectively.

Disclosed herein are dual stereoscopic image display apparatus and method. The dual stereoscopic image display method is performed by a dual stereoscopic image display apparatus, and includes separating a background image including a background and a foreground object image including a foreground object from multi-view stereoscopic image data, setting the background image so that the background image is output via a first display at a first resolution, and setting the foreground object image so that the foreground object image is output via a second display at a second resolution, and synchronizing the background image and the foreground object image into a single stereoscopic image via the first display and the second display, and outputting the stereoscopic image.

A stereoscopic video playback device is provided that processes original stereoscopic image pairs taken using parallel-axis cameras and provided for viewing under original viewing conditions by scaling and cropping to provide new viewing condition stereoscopic video on a single screen.

An image display apparatus according to an embodiment of the present technology includes an optical modulator, an optical device, and a sensor unit. The optical device splits a modulated light beam modulated by the optical modulator into a first split light beam and a second split light beam, the first split light beam and the second split light beam each travelling in a different direction, and prevents a light beam, which backwardly travels on an optical path of the first split light beam and enters the optical device, from travelling along an optical path of the second split light beam. The sensor unit is disposed on the optical path of the second split light beam and detects a state of the second split light beam.

The present disclosure related generally to techniques for improving the performance and efficiency of display systems, such as laser scan beam display systems or other types of display systems (e.g., micro-displays). Display systems of the present disclosure may include a polarization compensation optic, such as a spatially varying polarizer, that provides phase retardation that varies as a function of position, which provides polarization compensation to provide light that is well suited for a polarization sensitive optic of the display system, such as a waveguide-based optical system, a pancake optical system, a birdbath optical system, a coating-based optical system, etc. The display systems of the present disclosure may be components of head-mounted display systems, or other types of display systems.

A display system for a providing a three-dimensional effect with controlled reflections is disclosed. In one embodiment, the display system includes a display; and a beam splitter positioned between the display and the viewing location. The beam splitter transmits or reflects light based on a characteristic of the light. A physical prop is positioned between the beam splitter and the viewing location. The display is oriented to emit light toward the beam splitter and displays an image at least partially viewable in the viewing location through the beam splitter, such that the image is substantially un-attenuated by the bean splitter. Light reflected from the physical prop and further reflected by the beam splitter toward the viewing location is at least partially viewable in the viewing location. The display system is suitable to enable a substantially full brightness of the image to be viewable in the viewing location.
