Optical Diffusers Improve Definition, Viewing Angle for 3D Holograms

Facebook X LinkedIn Email
DAEJEON, South Korea, Feb. 17, 2017 — A wavefront-shaping technique has been used to create a dynamic 3D holographic image with a viewing angle of 35 degrees in a volume of 2 cm in length, width and height. Use of the technique was shown to yield a 3D holographic display that performed with more than 2600 times the strength of existing displays. Current 3D hologram technology relies on wavefront modulators to control the direction of light propagation. One limitation to using modulators as 3D displays is pixel number. The large number of pixels that are packed into high-resolution displays are suitable for a 2D image....Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
