LGS-2 Kev Sim Tshuaj CCD Spectrometer
Kev piav qhia
LGS-2 Experimental CCD Spectrometer yog ib lub cuab yeej ntsuas dav dav. Nws siv CCD ua lub cuab yeej txais kom nthuav dav nws qhov kev siv, muaj peev xwm txais tau lub sijhawm tiag tiag thiab tso saib 3-dimensional. Nws yog cov khoom siv zoo tshaj plaws rau kev kawm txog cov spectra ntawm cov teeb pom kev zoo lossis calibrating optical probes.
Nws muaj cov grating monochromator, CCD unit, scanning system, electronic amplifier, A/D unit thiab PC. Cov cuab yeej no sib xyaw ua ke optics, precision machinery, electronics, thiab computer science. Lub optical element siv CT model uas tau qhia hauv qab no.
Qhov tawv ntawm lub monochromator zoo thiab txoj kev teeb pom kev ruaj khov heev. Ob qho tib si nkag thiab tawm silts yog ncaj nrog qhov dav txuas ntxiv hloov kho tau los ntawm 0 txog 2 hli. Lub teeb hla dhau qhov nkag S1(S1yog nyob rau ntawm lub dav hlau focal ntawm daim iav reflectance collimation), ces reflected los ntawm daim iav M2Lub teeb sib luag tua mus rau lub grating G. Daim iav M3tsim cov duab ntawm lub teeb diffraction los ntawm lub grating ntawm S2los yog S3(daim iav hloov pauv M4tuaj yeem sau qhov tawm ntawm qhov, S2los yog S3). Cov cuab yeej siv lub tshuab sine los ua kom tiav qhov kev ntsuas wavelength.
Qhov chaw zoo tshaj plaws rau cov cuab yeej siv yog qhov chaw kuaj mob ib txwm muaj. Thaj chaw yuav tsum huv si thiab muaj qhov kub thiab txias ruaj khov. Cov cuab yeej siv yuav tsum nyob rau ntawm qhov chaw tiaj tiaj (txhawb nqa tsawg kawg 100Kg) nrog rau qhov chaw ib puag ncig rau cua thiab kev sib txuas hluav taws xob tsim nyog.
