Detailed description of the invention
Referring to Fig. 1, it is that optical system of the present invention is in the system concept schematic diagram of a preferred embodiment.Optics
System 1 includes luminous source 11, reflective structure light generating element 12 and senses judgment means 13, and instead
Penetrating formula structure light generating element 12 is to arrange (as attached, printing) in tested target 2, to use confession
The light beam 41 that luminous source 11 is provided is projected on it；Wherein, reflective structure light generating element 12 is in sending out
Produce structure light (structure light) 42 when the light beam 41 that light source 11 is provided is projected on it, and give
Reflex to a surface under measurement 3 so that surface under measurement 3 presents corresponding to reflective structure light generating element 12
Tested pattern 43, senses judgment means 13 then in order to sense the tested pattern presented on surface under measurement 3
43, and judge tested target 2 classification according to the tested pattern 43 sensed.
In this preferred embodiment, luminous source 11 can include laser diode (LD), light emitting diode (LED)
And at least one in Organic Light Emitting Diode (OLED), and/or luminous source 11 may also include and be similar to
Other luminescence unit of the semiconductor type such as laser diode, light emitting diode and Organic Light Emitting Diode；And
The light beam 41 that luminous source 11 is exported can be to have the light beam (such as visible light beam) of first wave length and/or have
The light beam of second wave length (such as invisible light beam or the light beam with thermoinduction range of wavelengths).
Secondly, reflective structure light generating element 12 can be a reflective diffraction optical element (DOE), and
It includes respectively in order to receive the light beam 41 belonging to different wave length frequency band and to produce structure light 42 to reflex to be subject to
Survey multiple working linings 121 on surface 3.Wherein, surface under measurement 3 is projected on it present because of structure light 42
Tested pattern 43 corresponding with the structure of reflective diffraction optical element 12, say, that this technology lead
Territory those of ordinary skill all can design the structure of reflective diffraction optical element and make according to practical situations
Required tested pattern 43 is presented on surface under measurement 3.For example, in response to reflective diffraction optics unit
The structure design of part, the pattern that surface under measurement 3 is presented can be bar code (bar code) pattern or quick
Answer code (QR code) pattern, or it is the pattern being varied from response to different viewing angles.Only,
How to make to present on surface under measurement 3 required being subject to through the structure of design reflective diffraction optical element
Mapping case 43 is known by the art those of ordinary skill, is the most no longer repeated at this.
Furthermore, in this preferred embodiment, sensing judgment means 13 includes sensing unit 131, judging unit
132 and high in the clouds pattern database 133, and high in the clouds pattern database 133 includes multiple data base's pattern
1331, and sensing unit 131 can be charge coupled cell (CCD) or CMOS
Element (CMOS), but be not limited with above-mentioned, and it can be light sensation seen from response to the kenel of luminous source 11
Answer unit and/or a black light sensing unit, be primarily used to capture presented on surface under measurement 3 tested
Pattern 43；Wherein, sensing unit 131 is after capturing the tested pattern 43 presented on surface under measurement 3, thoroughly
Cross wired mode or wireless mode and the tested pattern 43 captured is sent to judging unit 132, now, sentence
It can be carried out by disconnected unit 132 with the multiple data base's patterns 1331 in the high in the clouds pattern database 133 of rear end
Comparison, and then judge the classification of tested target 2.
Next the application of above-mentioned optical system 1 is illustrated.The application here enumerated is the true of steamed crab
Pseudo-identification, owing to steamed crab has fine and tender taste, delicious flavour, the characteristic such as nutritious, becomes and is much greedy for money or food
Visitors, in the favorite of autumn and winter, also thus result in driving up in price, and wherein, unworthy dealer often seizes the opportunity with incoming road
Not clear Eriocheir sinensis product counterfeit is palmed off as, or uses without quarantine or the smuggling Eriocheir sinensis of medicine inspection, uses the substantial amounts of profit of acquisition
Profit.In order to ensure that the rights and interests of consumer, with healthy, allow consumer can clearly identify the steamed crab to be bought
The true and false the most important, and the present invention i.e. provides a kind of mode identifying the steamed crab true and false.
Furthermore, be responsible for keyholed back plate steamed crab competent authority can stick on approved qualified steamed crab through
Cross the reflective structure light generating element 12 of particular design, and this produces through the reflective structure light of particular design
Raw element 12 is that the light beam 41 provided by luminous source 11 for dealer or buyer is projected on it and gives
Reflex to surface under measurement 3, make on surface under measurement 3, to present specific tested pattern 43.Wherein, dealer is worked as
Or buyer passes through the tested pattern 43 and high in the clouds presented on the surface under measurement 3 that sensing unit 131 is captured
Data base's pattern stored in pattern database 133 1331 (that is approved qualified steamed crab institute is due
Pattern) when matching, just can determine that it is approved qualified steamed crab securely.Additionally, due to by mark
2 be food, therefore the reflective structure light generating element 12 being arranged in tested target 2 is required to be edible unit
Part, high temperature resistant element etc. be not to injure the element made by the material of human body.
Certainly, although above-mentioned citing is the true and false identification of steamed crab, but is not limited thereto, and the most also may be used
Optical system 1 is applied to the true and false identification of natural striking kingfisher or natural gemstone.Although also, above-mentioned optical system 1
Being the true and false being applied to judge tested target 2, but be not limited thereto, such as optical system 1 also can be applied
In judging that tested target 2 produces the classification in the logistics such as time, the place of origin, such as, optical system 1 is applied
On the engine of automobile or the information labeling of tire.Also embodiment, this technology is come under additionally, described above
Field those of ordinary skill all can carry out the design for change of any equalization according to practical application request, and citing comes
Saying, change and be designed as, reflective structure light generating element 12 is only to receive the monolayer knot of single wavelength frequency range
Structure；The most for example, change and be designed as, sense the sensing unit 131 of judgment means 13, judging unit
132 and high in the clouds pattern database 133 be the device being integrated into single main body.
According to above explanation, the classification determination methods of tested target refers to flow chart as shown in Figure 2,
Wherein, the method includes: step P1, arranges reflective structure light generating element 12 in tested target 2；
Step P2, the reflective structure light generating element 12 on projecting beam 41 to tested target 2, wherein, instead
Penetrate formula structure light generating element 12 after receiving light beam 41, produce structure light 42, and it is tested to be reflexed to one
Surface 3, and when structure light 42 reflexes to surface under measurement 3, surface under measurement 3 can present and correspond to instead
Penetrate the tested pattern 43 of formula structure light generating element 12；And step P3, sensing surface under measurement 3 on institute in
Existing tested pattern 43, and judge the classification of tested target 2 according to the tested pattern 43 sensed.
The foregoing is only presently preferred embodiments of the present invention, be not limited to scope of the presently claimed invention,
The most all other changes without departing from the equivalence completed under disclosed spirit or modifies, and all should comprise
In the scope of patent protection of the present invention.
