Rayvel Adds Another Patent To Its Intellectual Properties Portfolio

Montville, CT — Rayvel, a corporation specializing in advanced holographics, has been awarded a patent for its wide angle hologram technology, enabling the production of compact, true holographic displays.

A hologram appears when it is illuminated from a light source at an angle that is determined during the manufacturing process. Typically it is a source at about a 45 degree angle from the hologram. It also usually needs to be placed at a distance from the hologram: the larger the hologram the further away the light source needs to be. This new invention allows the light source to be nearly parallel and close to the hologram, allowing the design of significantly flatter image display systems, useful for advertising signage, point-of-purchase, and trade shows.

“Over the past few years the term “hologram” has been used to describe several simulated 3D techniques and projection systems,” comments Joe Ciaudelli, President of Rayvel. “However, a true, classic hologram has unique characteristics beneficial for many image display and industrial applications.” Two of those characteristics are parallax and redundancy. Parallax means that different sides of the recorded holographic image can be observed from alternate viewing positions. For example, with a true holographic image of dice, an observer on the left would see different numbers on the dice faces than an observer viewing it from the right of the hologram. Redundancy is the property where every portion of the hologram contains all the recorded information. In other words, if a hologram is cut into a thousand pieces, each piece still has the whole holographic image. “This invention permits these and other distinct attributes of true holograms to be leveraged in a wider variety of enclosures,” adds Tom Cvetkovich, Master Holographer.

Rayvel also has patents for their inventions related to Narrow Angle Holograms. This technology illuminates a hologram from a perpendicular light source, such as a headlight from an oncoming vehicle. This is used in their Holocator™ product, street address numbers that aid visitors or emergency vehicles find a specific house in dark suburban or rural neighborhoods, no battery or other powering required. This technology can also be used for critical angular alignment of objects moving towards each other, such as a space craft trying to dock squarely with the space station.

Rayvel engineers also innovated the OTS 2000 automated optical test station. Designed for use in scientific clean rooms, this system fully analyzes optics, holographic optical elements, solar panels, etc. and maps defects as small as 1 micron (the diameter of human hair is about 100 microns).

“We are very pleased with the award of our latest patent by U.S. Patent and Trademark Office. It is an exciting time to be in the field of advanced holographics and we are committed to continued innovation,” states Ciaudelli.
