Abstract
The gemstone recordal and retrieval system records optical images for gemstones in an effective manner. The optical image of a gemstone is captured using a two-dimensional charge coupled device whereby the time to capture the image is relatively short. The optical images can be improved in definition by varying the output of a laser LED. This fast feedback and adjustability provides accurate recordings.
Claims13
A gemstone recordal system which records a unique light pattern of a gemstone comprising
- a site computer having means for receiving a data signal from a two-dimensional video camera,
- said two-dimensional video camera being part of a light image capture arrangement comprising
- a light emitting laser diode in combination with optical means for producing a collimated light beam directed at a gemstone fixture,
- said gemstone fixture orientating a gemstone in a predetermined manner relative to the collimated light beam, and a screen surface onto which the unique light pattern from a gemstone is collected,
- said video camera being directed at said screen surface and being sized to capture the unique pattern simultaneously,
- said computer correcting said signal from said video camera for known distortions introduced due to an angular position of said video camera relative to said screen surface and producing a digital signal of said unique pattern on said computer for review and approval by a user,
- said computer including means to have a user input and associate characteristics of the gemstone producing the image with said digital signal thereby producing a combined signal and a printer for producing a certificate identifying the characteristics and reproducing the corrected unique pattern,
- said computer forming a communication with a predetermined computer database and outputting said combined signal to said predetermined computer database which records said combined signal in a standardized manner.
A device for producing a reproducible identification pattern of a polished gemstone comprising
- light directing means for directing a collimated beam of light onto a gemstone orientated in a particular known manner to produce an optical output of the internal refraction and reflection characteristics of the gemstone,
- means for capturing a selected portion of the output in a manner to establish the relative size and location of the reflected light beams, wherein said capturing means is a video camera and said light directing means is a light emitting laser diode having associated therewith optical means for collimating the output.
A method of recording an optical image of a suitable substance comprising:
- producing and displaying an optical image of the substance which has been exposed to the output of a stimulating laser,
- initially capturing the optical output using a video camera,
- displaying the captured optical image and providing an exposure control which varies the output of the stimulating laser for improving definition of the optical image,
- approving a captured optical image for recordal,
- correcting the approved captured optical image for an angular orientation of the video camera relative to the displayed optical image, and
- simplifying and classifying the displayed optical image to precisely locate and size hot spots in the captured optical image and recorded the same in a digital signal, and store the digital signal in a database for future retrieval.
