Description
Technical field
The utility model is related to spectrometer technical field, especially a kind of mobile phone spectrometer.
Background technology
Spectral technique as the fields such as food inspection, environment measuring, biochemical analysis, biomedicine important detection technique hand
Section, the requirement more and more higher with people to the real-time of testing result, testing staff needs carrying spectrometer to enter when many
Row detects is detected again after being gone back rather than sampling that on the spot this causes the spectrometer equipment of original heaviness also toward becoming for minimizing
Gesture is developed.
Along with the arrival in mobile Internet epoch, the mobile device with mobile phone as representative early has evolved into current main flow
IDT, the various equipment combined with mobile phone constantly release, allow collection that it completes various sensing datas, point
Analysis, upload etc..Because the optical element of micro spectrometer can be as a single hardware system, therefore can be by itself and hand
Machine is coordinated, and the image of spectrometer input is gathered using mobile lens, using mobile phone display screen curtain as spectrometer collection figure
The display terminal of picture, therefore optical module need to be only fitted to each other with mobile phone, then it is aided with mobile phone terminal software, you can realize mobile phone light
Spectrometer.
For existing micro spectrometer, mobile phone spectrometer is in the aspect nothing such as portability, cost and data transfer
Doubting has very big advantage, but spectrometer, used as detecting instrument, no matter how its structure type changes, it is necessary to possess certain
Spectral resolution could obtain good accuracy of detection, and seen mobile phone spectrometer is generally that optical fiber shines directly on the market at present
On grating, then it is imaged on the imaging sensor of mobile phone through mobile lens after plane transmission grating diffraction, due to treating light-metering
Be it is not collimated just project on grating, and after optical grating diffraction cannot short distance formed focus on, the spectrogram for so obtaining
As resolution ratio is often undesirable.
Color dispersion-type spectrometer is, by secondary color optical dispersion, to be divided into sequence spectral line, then using dispersion element for from principle
Again with the intensity of detector measurement each spectral line unit, interference type spectral instrument be while measure the interference strength of all spectral lines units, it is right
Interference pattern carries out target light spectrogram obtained from inverse Fourier's series.
Theory analysis shows, under the same conditions, an interference type spectral instrument luminous flux 200 times left side high compared with color dispersion-type spectrometer
The right side, spectral resolution is typically also wanted more than 2 orders of magnitude high.
The content of the invention
In order to solve the deficiencies in the prior art, it is strong, easy to use that the utility model provides a kind of high resolution, portability
Mobile phone spectrometer.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is：A kind of mobile phone spectrometer, including mobile phone
With the optical lens for being placed in mobile lens front end, described optical lens include lens barrel and in lens barrel along light beam incident direction according to
Polarizer, Amici prism, analyzer, the first shrink beam eyeglass and the second shrink beam eyeglass that sequence is set, the second described shrink beam eyeglass
Diameter is less than the first shrink beam eyeglass, and the second described shrink beam eyeglass is just right with mobile lens, and described mobile phone also includes being located at hand
Machine camera lens rear end is used for the imageing sensor being imaged and is pre-stored in the software in mobile phone for output spectrum image.
Further, described polarizer front end is additionally provided with the collimating mirror for optical signal collimation.
Further, described Amici prism is Rochon prism or Wollaston prism.
Further, described imageing sensor is CCD or CMOS.
Preferably, described imageing sensor is area array CCD or face gust CMOS.
Using above-mentioned technical scheme, the beneficial effects of the utility model are：The letter to be measured that will can be dissipated by collimating mirror
Number light collimation is directional light, improves the quality of incoming signal light, recycling be made up of Rochon prism or Wollaston prism point
Light after beam splitting is adjusted to direction of vibration identical polarised light by flashlight beam splitting by light prism by analyzer, by the first contracting
Beam eyeglass is projected in mobile lens by the second shrink beam eyeglass again after carrying out shrink beam, image is imaged on the image in mobile phone and is passed
On sensor, can make that the image resolution ratio for collecting is higher using the combination of Amici prism and shrink beam eyeglass, image quality is more preferable.
Brief description of the drawings
The utility model is further elaborated with reference to the accompanying drawings and detailed description：
Fig. 1 is the simplified diagram of the utility model device.
