Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

Holography
Holography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that when an imaging system is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present...

As a physicist, Cross' research started in the 1950s, and focused primarily on maser
Maser
A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission. Historically, “maser” derives from the original, upper-case acronym MASER, which stands for "Microwave Amplification by Stimulated Emission of Radiation"...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of photons. The term "laser" originated as an acronym for Light Amplification by Stimulated Emission of Radiation...

 sculptor Gerry Pethick, developed a simplistic stabilization system for holographic cameras, that for the first time did not require expensive optics and an isolation table, effectively making the medium accessible to artists. In 1970, he organized the first exhibition of holographic art at Cranbrook Academy of Art in Bloomfield Hills, Michigan

. This success, and laser research turning to military applications which he didn't want to be part of, prompted him to leave the laboratory and tour for a short time with a laser and sound show.

Human eye
The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth...

Stereoscopy
Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth...

 works. His most famous work in this form was a hologram of a woman that appeared to wink and blow a kiss as the viewer walked by, entitled The Kiss. This historic piece can be viewed at the Massachusetts Institute of Technology (MIT) Museum, Cambridge, Mass.

In the mid 1970s, Cross founded the Multiplex Corporation, to find commercial applications and further develop his holographic techniques.
