Abstract
The utility model relates to the technical field of optics and especially relates to a double-beam synchronous triggering micro optical fiber spectrometer. The double-beam synchronous triggering micro optical fiber spectrometer comprises a main optical fiber which is connected to a xenon lamp module. The tail end of the main optical fiber is connected with two branch optical fibers through a splitter, the branch optical fibers are connected in a sample pool, and output ends of the sample pool are connected with input ends of the spectrometer through the branch optical fibers. The double-beam synchronous triggering micro optical fiber spectrometer has the following advantages: 1) synchronous triggering enables a lamp to be lighted only by pulse and greatly extends the service life of a light source; 2) synchronous triggering enables a system to complete effective data acquisition in the best period of time; 3) a double-beam working mode greatly reduces requirement on stability of the light source, and data accuracy is ensured through real-time data correction; and 4) the design of double optical paths in one machine reduces the requirement of the machine on the working environment.
Description
Technical field
The utility model relates to optical technical field, and especially a kind of twin-beam triggers micro fiber spectrometer synchronously.
Background technology
The spectral instrument basic equipment that to be applied optics technology, electronic technology and computer technology analyze and measure the composition of material and structure etc. is widely used in fields such as environmental monitoring, Industry Control, chemical analysis, food quality detection, material analysis, clinical examination, Aero-Space remote sensing and education of science.Owing to deficiencies such as traditional spectrometer exist complex structure, environment for use is limited, inconvenience is carried and expensive, can not satisfy the on-the-spot demand that detects and monitor in real time.Therefore fiber spectrometer just occurred, the development of fiber spectrometer technology makes determinand break away from the restriction in fixed sample pond, and it is more flexible that sample mode becomes, and is suitable for remote sample character surveillance.Though fiber spectrometer has had more advantage, but it still exists the some shortcomings part, measure substance characteristics in actual application by spectral absorption method at present, several big problems have been brought: 1, select for use old-fashioned monochromator to work in the mode of simple scan, picking rate is slow, and tested speciality composition is changed.2, because light source is high-power heater members, in test process, drift about easily, influence test result.3, spectrometer is as detection part, because working environment changes, causes forming that temperature is floated, drift etc., influences test result.
The utility model content
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, can realize effectively eliminating drift that the light source change brings and the fiber spectrometer of error.
For achieving the above object, the utility model has adopted following technical proposal: a kind of twin-beam triggers micro fiber spectrometer synchronously, comprise a main fiber, be connected on the xenon lamp module, it is characterized in that, described main fiber end links to each other with two branch optical fiber by splitter, divides optical fiber all to be connected in the sample cell, and the output terminal of sample cell is again by dividing optical fiber to link to each other with the input end of spectrometer.
Trigger synchronously in the micro fiber spectrometer at above-mentioned a kind of twin-beam, described input end is provided with two, links to each other with minute optical fiber respectively.
Trigger synchronously in the micro fiber spectrometer at above-mentioned a kind of twin-beam, comprise sample block and reference module in the described sample cell.
Compared with prior art, advantage of the present utility model is: 1, trigger synchronously, lamp only need be pulsed light, prolonged the life-span of light source greatly.2, trigger synchronously, make system finish the valid data collection with Best Times.3, twin-beam working method greatly reduces the requirement to light source stability, can guarantee the accuracy of data by data correction constantly.4, machine double light path design has reduced the requirement to the loom working environment.5, the AD that adopts two-way to share can directly remove AD chip itself to the influence of test result.6, the data recombination ability of spectrometer itself has been unified the interface to host computer, the software interface problem when making things convenient for the client to select for use.7, USB transmission at a high speed effectively guarantees the test of two-forty and the possibility of on-line monitoring.
