The ZL200910062640.4 patented claim discloses a kind of quick discriminating natural jadeite and instrument and the method that glue is handled emerald filled in pickling.The organic box of the employed discriminating instrument of this patented claim, machine box top is the darkroom, the location window of placing sample to be checked is arranged on the base plate of darkroom, there is hemispheric light source chamber the below, darkroom, have light source window and ultraviolet cutoff windowpane, under the light source window light source is installed, ultraviolet cutoff is equipped with photoelectric sensor outside glass window; Power switch, Test Switchboard and display are arranged on the panel of machine box, and microprocessor is connected with photoelectric sensor, power supply, switch, display, and microprocessor also can be connected with the computing machine of outside.Its testing process mainly is to reach the type that the time length that continues is differentiated emerald with the intensity that jade sample is subjected to being phosphoresced after the radiation.The used instrument of this patented claim is a kind of desktop computer of being convenient to observe on operator's console, the volume of its machine box is limited, carries inconvenience, and measuring ability is single, promptly can only be used for observing the less smallclothes emerald article of volume, and can not be used for carrying out the detection of other antiques class article.Therefore can not satisfy consumer and trader's use needs.
Summary of the invention
Purpose of the present invention just provides the method for quick of a kind of emerald, antiques, with the simplest mode emerald or antiques are carried out fast detecting, detects imitative product, avoids having dust thrown into the eyes.
The present invention is achieved in that the method for quick of a kind of emerald, antiques, detects and carries out according to the following steps:
A, the surface of inspected object is cleaned;
B, tester's handheld portable LED ultraviolet source shine the surface of inspected object, promptly have the hot spot of irradiation to produce on the surface of inspected object;
C, tester hand a ultraviolet filtering mirror and by the irradiation hot spot on this ultraviolet filtering mirror observation inspected object, the power of non-blooming generation and fluorescence generation are arranged on the observation irradiation hot spot;
D, mobile portable LED ultraviolet source or the inspected object that moves, overturns make portable LED ultraviolet source irradiation at the different surfaces of inspected object or the different parts on same surface, carry out multipoint observation.
The wavelength of the ultraviolet light that described portable LED ultraviolet source is sent is 360-400nm.
The wavelength of light of described ultraviolet filtering mirror institute filtering is 10-400nm.
Testing process is carried out at place indoor or backlight, avoids carrying out under direct irradiation of sunlight.Described inspected object is placed on the dark substrate.
Ultraviolet wavelength is 10-400nm, and spectrum is between visible light and X ray.Though its wavelength ratio visible light is short, can not arrive for human eye is observed, but the light reaction that a lot of materials are presented under the irradiation of ultraviolet light is different, particularly various pigment, wax and organic gel etc. are modelled after an antique, emulation is commonly used modern chemical industry synthetic material and macromolecular material, it all can send under the irradiation of ultraviolet light significantly or stronger Ultraluminescence, and this is main and tangible characteristics that are different from natural jadeite and genuine piece antique, calligraphy and painting.Therefore, detection method of the present invention just is mapped on the inspected object with the ultraviolet lighting that little, in light weight, luminous good, an easy to carry portable LED ultraviolet source of volume is sent out, to observe the effect of its fluorescence reaction.But, because ultraviolet source irradiation is more approaching to the sensory effects of the Ultraluminescence that ultraviolet reflectance light that inspected object surface produced and inspected object itself are produced, human eye is not easily distinguishable, so, the present invention uses a ultraviolet filtering mirror to carry out filtering preferably to ultraviolet reflectance light, and what can observe out on inspected object thus to be produced is ultraviolet reflectance light or Ultraluminescence on earth.If there is Ultraluminescence to produce, can affirm that inspected object handled through manual method, just belong to the modern times to imitate product.
Detection method of the present invention is not subjected to the restriction of instrument and equipment, and everybody can grasp and use, and the scene can be detected, operate very simple, and identification result quicklook; Owing to do not have the restriction of machine box cabinet etc., so big or small article all can arbitrarily detect.Detection method of the present invention is suitable for multiple article such as emerald, gambling stone, antiques, calligraphy and painting, strange stone and jewel are detected, and can satisfy multiple ornament or the consumer of collection and trader's use needs such as emerald, jewel, antiques, calligraphy and painting.
Description of drawings
Fig. 1 is a detection principle schematic of the present invention.
Embodiment
In conjunction with shown in Figure 1, detection method of the present invention is to carry out according to the following steps:
A, the surface of inspected object is cleaned;
B, at place indoor or backlight, the tester hands the portable LED ultraviolet source 1 that wavelength is 360-400nm, and the surface that is placed on the inspected object 3 on the dark substrate is shone, and produces the irradiation hot spot on the surface of inspected object 3;
