Description
Technical field
The present invention relates to a kind of spectrometer of releasing, particularly relate to the photon detection device of releasing spectrometer.
Background technology
After the crystalline solid that has stored emittance was accepted exciting of extraneous heat or light, the energy storage electronic reset of crystals was also eliminated its energy stored in the mode that discharges photon.What produce releases in the light, be heated excite and the photon that discharges is a thermoluminescence, be subjected to exciting of light and the photon that discharges is that light is released light.Crystalline solid release the essential characteristic that photon has reflected crystalline solid, the photon that is excited out is the different and different of the kind of foreign ion contained in constituent, structure and the crystal of crystal and content etc. with the essence of crystalline solid.Releasing spectrometer is the spectrometer that a kind of photon that crystalline solid is discharged is surveyed and analyzed.Since releasing spectrometer and coming out, have only two types release that the spectrometer instant heating is released spectrometer and light is released spectrometer.These the two kinds differences of releasing spectrometer are that crystalline solid discharges the exciting means difference of photon, the thermoluminescence spectrometer is to discharge photon because of crystalline solid is subjected to thermal excitation, it is to discharge photon because of crystalline solid is subjected to exciting of light that light is released spectrometer, and corresponding two kinds of structures of releasing spectrometer are also different.But no matter be that thermoluminescence spectrometer or light are released spectrometer, it is identical that ballistic phonon is surveyed the technological means of using, all be to use with the photomultiplier is that the photon probe of core devices is a sniffer, the photon probe is installed on the photon collecting chamber, the photon probe changes into electric pulse with the photon signal that detects, and is input to computing machine through the amplification shaping then and analyzes and handle.Owing to release spectrometer and all have only a photon probe for two kinds, adopt the single track photon counting, the result of acquisition is also can only be to total photon counting, can not measure simultaneously and analyze the photon of different frequency.
Summary of the invention
The object of the present invention is to provide a kind of improved spectrometer of releasing, the photon of the different frequency that it can discharge crystalline solid is measured simultaneously and is analyzed.
The object of the present invention is achieved like this:
The Light releasing photon frequency division spectrometer, comprise photon collecting chamber and photon probe, it is characterized in that this releases spectrometer and contain plural photon probe, corresponding with the photon probe, contain the cross section on the top cover of photon collecting chamber and be circular through hole, photon probe is consistent with the quantity of through hole, and the pop one's head in end that contains optical filter of photon passes on the top cover that through hole is connected the photon collecting chamber.
Further, contain sleeve pipe in the connected mode of photon probe of the present invention and photon collecting chamber top cover, have the evagination snap ring on the outside surface of sleeve pipe, curved filler ring in the one end has, sleeve pipe passes through hole and fixedlys connected with the top cover of photon collecting chamber by the evagination snap ring, the end that the photon probe contains optical filter inserts sleeve pipe, and the interior curved filler ring of sleeve pipe is held the head of photon probe, can finish photon probe mounting and dismounting easily by plug like this.For the Light releasing photon frequency division spectrometer, better technical scheme is that the head that the optical filter card is put device and photon probe is split, and the optical filter that this scale is put in the device just can be changed.Have, the sample from the sample drawer equates to the vertical range of each photon probe optical filter again.
Because photon probe is gone up the optical filter that card puts and can be changed, and prior art can will allow frequency limitation by the optical filter photon in a very narrow scope, and each photon probe frequency of receiving Light releasing photon just can be adjusted like this.A photon probe can receive a kind of light of releasing of frequency, contains plural photon probe and release spectrometer, and a plurality of photon probes just can receive the light of releasing of multiple different frequency simultaneously.The frequency that a plurality of photon probes receive Light releasing photon can have multiple array mode, and the density that increases the photon probe has also just improved the precision of surveying.
The photon that crystalline solid discharges has certain frequency range, the probability that the different frequency photon occurs is not average the same, but certain difference is arranged, the occurrence probability higher photon energy that compares more profoundly reflects and the feature of crystalline solid might as well be referred to as the feature photon.Feature photon notion is for many years the notion that proposes on the basis to be observed in the crystalline solid chamber of experimentizing the inventor, is the in-depth to crystalline solid understanding.The Light releasing photon of crystalline solid is the energy characterization of energy storage electronics in the crystalline solid, and under identical shooting conditions, the energy of ballistic phonon is to be directly proportional with the energy of energy storage electronics in the crystal.Therefore, the direct reflection of releasing energy storage electron energy in the crystal only of crystal, release spectrogram just in the crystal energy storage electronics can spectrogram.Characteristic light daughter with characteristic frequency is showing the energy distribution feature of energy storage electronics in the crystal, has shown the essence of crystal truly.
The light of essence, identification of Mineral and the mensuration at geological sample age etc. the proposition of this notion is released to(for) further investigation crystalline solid all have great importance, and the present invention is exactly and the corresponding a kind of design proposal of feature photon notion.Just because of this, the photon detection equipment that adopts of the present invention and each laboratory in the past is essentially different.The photon that application the present invention ejects crystalline solid carries out frequency division to be received and handles, and can determine the feature photon that crystalline solid discharges under certain shooting conditions.The feature photon that different crystalline solids discharge under identical shooting conditions generally is different, and the difference of feature photon reflects the difference of Light releasing photon energy, and what further embody is the difference of energy storage electron energy.The existing optical measuring device of releasing all can't observe this feature photon and energy state thereof, because the detector of the reception photon that they adopted all is single, the optical filter of employing also is the broadband, can't distinguish characteristic wavelength.
The photon that the Light releasing photon frequency division spectrometer can discharge crystalline solid carries out frequency-selecting and receives, and counts respectively and handle, and is actually a multiple tracks photon numeration and disposal system.By multiple tracks numeration storage and analyzing and processing to the crystalline solid Light releasing photon, the frequency division that just can obtain a crystalline solid is released spectrogram, and the peak value from spectrogram just can be determined the feature photon.The photon that a kind of crystalline solid discharges generally has wider frequency, and often has the feature photon of multiple different frequency, and these feature photons just are contained in releasing in the light of crystalline solid.Under the situation that obtains specific crystalline solid feature photon, by the present invention the feature photon of this kind crystalline solid single-frequency is carried out again that multiple spot is measured simultaneously or the feature photon of different frequency is measured simultaneously and analyzed, can obtain more valuable information.
Release and comprise feature photon phenomenon in the light and when geological sample is carried out age determination with the thermoluminescence technology, find, and, at first just in the laboratory, it is used for the age determination of geological sample, and has obtained success.Release optical tech with Ricoh and also should develop into a kind of effective technology that solves geological sample age determination problem more exactly.For release improved Light releasing photon frequency division spectrometer on the spectrometer basis at light, it has kept the advantage that light is released spectrometer, as can from geological sample, determining the mineral at optimum determining age at selectable excitation source, make the age data of gained genuine and believable, increase new intension again, compare mutually, verify as the survey data in age that can obtain respectively, thereby improve the confidence level that mineral are surveyed age the feature photon that utilizes different minerals in the same geological sample.Particularly, the frequency of the feature photon of different minerals generally all is different, can carry out frequency division at the feature photon of different minerals in the same geological sample simultaneously by the present invention surveys and analyzes, and the survey result in age who obtains respectively carry out mutually than, verify, eliminate the false and retain the true, can improve the confidence level of surveying the result in age.In addition, can carry out that frequency division is surveyed at the different characteristic photon of same mineral in the same geological sample simultaneously and analyze, and the survey result in age who obtains is respectively carried out mutually also further improving survey result's in age confidence level than, checking by the present invention.Therefore, the survey annual data that uses the present invention to obtain accuracy and confidence level that flash ranging year is released in raising has important scientific value and practical significance.When application Light releasing photon frequency division spectrometer carries out age determination to geological sample, be a kind of survey year technology of novel concept.
Because release the luminosity that mineral itself are only had, under certain condition, each mineral all has the feature of oneself to release spectrum.The feature of mineral is released spectrum except outside the Pass having with the structure of mineral and composition, also relevant with the impurity content in the mineral, the elemental characteristic of impurity and content all have direct effect to the spectral pattern of releasing spectrum and the intensity of mineral in the mineral, therefore, utilize feature to release the important means that spectrum can become mineralogical analysis and evaluation.
