Kev xaiv wavelength thiab Spectroscopy: Lub luag haujlwm tseem ceeb tshaj plaws ntawm lub teeb pom kev zoo yog kom decompose polychromatic lub teeb rau hauv lub teeb monochromatic. Nws qhov tseeb spectroscopic yog txiav txim siab los ntawm grating ntom (kab khub / hli) thiab cov khoom siv grating.
Beam Deflection thiab Scanning: Los ntawm rotating lossis txhais cov grating, cov kev taw qhia ntawm lub teeb diffraction tuaj yeem hloov pauv hloov pauv, ua tiav beam scanning. Piv txwv li, nyob rau hauv laser luam ntawv tshuab, kev xav gratings vibrate ntawm ib zaus ntawm ntau txhiab lub sij hawm ib ob, projecting lub laser beam rau txawv txoj hauj lwm los tsim cov cim los yog cov duab; Nyob rau hauv astronomical telescopes, gratings ua ke nrog rotating iav tuaj yeem ua tiav cov hnub qub taug qab kev soj ntsuam.
Phase Modulation thiab Wavefront Correction: Cov kev xav tau siab tshaj plaws tuaj yeem hloov kho cov theem ntawm lub teeb nthwv dej los ntawm tsis yog -cov khoom siv grating, siv rau laser tsom, holographic imaging, los yog optical xam. Piv txwv li, nyob rau hauv ultrafast laser systems, theem modulation gratings yuav compress femtosecond pulses mus rau ib lub sij hawm (<5 fs), breaking through traditional optical limits.
Intensity Distribution Control: Los ntawm kev tsim lub voj voog lub luag haujlwm ntawm cov kab grating grating, kev siv hluav taws xob faib hluav taws xob tuaj yeem tswj tau. Piv txwv li, hauv kev sib txuas lus kho qhov muag, 8: 2 lub luag haujlwm lub voj voog grating tuaj yeem ua ob peb 90% ntawm lub teeb siv rau xoom-kev txiav txim siab, nrog rau 10% ntxiv siv rau kev soj ntsuam teeb liab, yog li ua tiav kev faib hluav taws xob kho qhov muag tau zoo.
