Description
Technical field
The utility model belongs to Medical Instruments.
Background technology
Along with enhancing and the increase of advanced detection means of health of people consciousness, the melanoma cases that China makes a definite diagnosis out also in continuous increase, approximately with annual 3% to 8% speed increment; In addition, along with environmental pollution increases the weight of, ultraviolet irradiation amount increases day by day, too increases the melanomatous risk of Chinese population suffering from skin." report of world's cancer " indication of the World Health Organization (WHO), the following several years will be the global skin neoplasin patient time occurred frequently, the annual newly-increased cancer patient's number in the whole world will reach 1,500 ten thousand people, die from cancer occurrence numbers more than 600 ten thousand, the incidence to the year two thousand twenty global range Malignant skin tumor will increase by 50% again.Early diagnosis, early treatment are the most effectual ways of effectively curing malignant mela noma.According to statistics, patients survive's probability of 5 years of making Diagnosis and Treat is in early days 95%, otherwise patients survive's probability of 5 years is only 50%.Data shows, the survival period of skin neoplasin patient directly depends on state of an illness during diagnosis, early diagnosis and therapy can fully recover about 1/3rd patient, and clinic skin tumor imaging detects the patient found and has often been in cancer middle and advanced stage and has can not be restored.Therefore, study skin cancer technique for detection to have very important significance.
At present, develop various skin tumor imaging device both at home and abroad and applied for patent.(patent No.: 200610063723.1), it irradiates by rotatory polarization light the information that skin histology obtains different polarization angle for the linear polarization formation method of a kind of epithelial tissue that such as (1) Tsing-Hua University proposed in 2007 and device.(2) subsidiary/member companies of Xi'an ray machine institute proposed a kind of epithelial tissue canceration getting up early diagnostic system (patent No.: 201220587454.X) in 2013, and it is the information being analyzed epithelial tissue by the residual quantity of different polarization states light.(3) company of Israel proposed in 2013 a kind of skin surface optical polarization imaging system (patent No.: 201280016358.2), it be by change polarization state obtain the scattered light of tissue surface in real time thus obtain corresponding information.
But above-mentioned polarization imaging method is all adopt to change different polarization states to obtain the polarization angle information of tissue, because polarization information also has polarization intensity and polarization angle information, these methods are difficult to the comprehensive polarization information obtaining biological tissue, and these methods above-mentioned have significant limitation.
Summary of the invention
The utility model provides a kind of skin neoplasin imaging device, to solve the problem that the comprehensive polarization information of skin neoplasin obtains difficulty.
The technical scheme that the utility model is taked is: centre wavelength is the level crossing that the semiconductor laser front end light path of 650nm has focal length is the concavees lens of 20mm, focal length is 80mm convex lens, the polarizer respectively and places in miter angle α, above this level crossing, have analyzer, focal length to be lens and the charge-coupled image sensor of 60mm, this polarizer, analyzer and charge-coupled image sensor are electrically connected with computer respectively.
Described level crossing has plated anti-reflection film by half, half plated the anti-film of increasing eyeglass composition.
The utility model advantage is novel structure, imaging clearly, and resolution is high, and imaging is accurate, and save time, equipment use is flexible.Realized polarization intensity, polarization angle, the polarization degree information of skin neoplasin pathological tissues by control analyzer and the polarizer, accurate imaging can be carried out in early days in skin neoplasin pathology, thus obtain the skin neoplasin organizational information of comprehensive and abundant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Centre wavelength is the level crossing 5 that the semiconductor laser 1 front end light path of 650nm has focal length is the concavees lens 2 of 20mm, focal length is 80mm convex lens 3, the polarizer 4 respectively and places in miter angle α, above this level crossing 5, have analyzer 7, focal length to be lens 8 and the charge-coupled image sensor 9 of 60mm, this polarizer 4, analyzer 7 and charge-coupled image sensor 9 are electrically connected with computer 10 respectively.
Described level crossing 5 has plated anti-reflection film 502 by half, half plated the anti-film 501 of increasing eyeglass composition.
In FIG, employing centre wavelength is the semiconductor laser 1 of 650nm, first the incident light of its 6mm size produced is the concavees lens 2 of 20mm by focal length, the convex lens 3 being 80mm by focal length again become parallel beam, then the polarized light of certain orientation is formed by the polarizer 4, and then having anti-reflection and increasing anti-level crossing 5 by 45 degree of α angles placements, on the sample 6 of parallel polarized light vertical irradiation skin neoplasin diseased region, in the direction on vertical sample surface, the back-scattering light of the different polarization states that sample returns is first by analyzer 7, the scattered light determining polarization state is allowed to pass through, and then be the lens 8 of 60mm by focal length, last charge-coupled image sensor (CCD) 9 collection information is also stored on computer 10, wherein the polarizer 4 and analyzer 7 are the polarized lights being arranged different polarization states by computer 10.
