The word "speckle" is correct and usable in written English.
You can use it when referring to a dispersed pattern of spots, such as a speckled floor or speckled eggs. For example, "The speckled eggs were a delight to the eye."
This is because, during the original scan, the detectors pick up such a large amount of information that a re-scan need provide only part of the speckle pattern for a reliable comparison to be made.
Variations in the speckle are then digitised to produce a code that is unique to the scanned item.
By detecting the change in this speckle, it is possible to chart the texture of the surface.Ingenia's machines use a scanning head consisting of three small lasers and six detectors to examine part of an object.
That done, the white laser light is filtered back into red, green and blue light and projected using the DLP system.Dr Bi has, however, gone further than just eliminating speckle.
By analysing this speckle, it is possible to chart the texture of the surface.Ingenia's machines use a scanning head consisting of three small lasers and six detectors to examine part of an object.
Some of the tiny island states that speckle the map of the Pacific also make uncomfortable neighbours.
The second problem, though, is that laser light can "speckle", which is to say that when it scatters off a rough surface, a random shimmering and sparkling pattern is produced.
Indeed, as Italy's medium-sized industrial firms adapt to the threat from China, the benefit they get from being bunched together in a cluster seems to be weakening.More than 100 such clusters speckle the boot of Italy: tiles in Sassuolo, food machinery in Parma, sofas in Matera, footwear in Fermo and clothing in Treviso, to name just some.
THE SWEET PERFUME wafting over northern Iraq does not come from the wildflowers that speckle its rumpled plains in spring.
The speckle is a scattering of light caused by micron-sized ridges and groves on an object's surface.
And a fast, low-cost way of doing just that has now been commercialised by Ingenia Technology, a company based in London, to provide what it calls a tamper-proof method of "laser surface authentication".The process was developed initially at Imperial College, London, and is based on a phenomenon known as laser speckle.
