Gregg E. Favalora, Optics for Hire

Clever use of electro-optics, lens arrays, diffusers and software advances the multidimensional way of seeing The broad field of autostereoscopic display – the creation of imagery that appears three-dimensional without requiring the use of additional eyewear1,2 – is evolving. Optical engineers continue to push 3-D display technologies to match depictions in science fiction movies. It’s 2012, after all – can’t one simply buy a “holographic video display” that snaps into a DVI port and generates a cubic meter of full-color, occlusion-bearing,...Read full article

    Glossary
    electro-optics
    1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material; 2. Collectively, the devices used to affect the intersection of electrical energy and light. Compare with optoelectronics.
    microelectromechanical systems
    Refers to micron-size complex machines that have physical dimensions suitable for the fabrication of optical switches for use in state-of-the-art communications networks.
    parallax
    The optical phenomenon that causes relative motion between two objects when the eyepoint is moved laterally. When parallax appears in a telescope between the image and reticle, this indicates the image has not been formed in the plane of the reticle.
    sharp
    A term used to describe a convex surface having too short a radius of curvature. To correct this condition, material is cut from the outer portion of the polishing tool.
