  2. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two. The 3D scene in an autostereogram is often unrecognizable until it is viewed properly, unlike typical stereograms.

  3. 3D stereo view - Wikipedia

    en.wikipedia.org/wiki/3D_stereo_view

    In other words, the degree of decoupling between focusing and convergence needed to visualize an autostereogram is reduced. This places less strain on the brain. Therefore, it may be easier for first-time autostereogram viewers to "see" their first 3D images if they attempt this feat with bright lighting.

  4. Autostereoscopy - Wikipedia

    en.wikipedia.org/wiki/Autostereoscopy

    Comparison of parallax-barrier and lenticular autostereoscopic displays. Note: The figure is not to scale. Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer.

  5. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

    The American Registry for Diagnostic Medical Sonography (ARDMS), incorporated in June 1975, is an independent nonprofit organization that administers examinations and awards credentials in the areas of diagnostic medical sonography, diagnostic cardiac sonography, vascular technology, physicians’ vascular interpretation, musculoskeletal sonography and midwifery ultrasound.

  7. Stereoscopy - Wikipedia

    en.wikipedia.org/wiki/Stereoscopy

    Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.

  9. Random dot stereogram - Wikipedia

    en.wikipedia.org/wiki/Random_dot_stereogram

    To view the stereogram, use a stereoscope to present the left image to the left eye and the right image to the right eye or focus on a point behind the image to achieve the same thing. (How to achieve this wall-eyed position of the eyes is described in Autostereogram). The shifted region of random dots will appear as a small, central, square ...
