Nyob rau hauv optics, chromatic aberration, kuj hu ua chromatic distortion thiab spherochromatism, yog ib tug tsis ua hauj lwm ntawm lub lens los tsom tag nrho cov xim rau tib lub ntsiab lus. Nws yog tshwm sim los ntawm dispersion: lub refractive index ntawm lub lens ntsiab nws txawv nrog lub wavelength ntawm lub teeb.
txhais li cas los ntawm monochromatic aberration?
Dab tsi yog monochromatic aberrations? Monochromatic aberrations yog aberrations uas tshwm sim hauv lub teeb quasimonochromatic. � Cov aberrations no tsis xav txog qhov cuam tshuam qhov zaus ntawm lub teeb muaj nyob rau hauv nws propagation los ntawm ib tug system. (Lub teeb tiag tiag yeej tsis monochromatic - nws ib txwm yog ua los ntawm ib pawg ntawm cov zaus.
Chromatic aberration yog dab tsi?
Chromatic aberration, xim distortion hauv ib daim duab saib los ntawm iav lo ntsiab muag. … Qhov kev hloov ntawm cov duab nyob deb nrog wavelength yog hu ua chromatic aberration, thiab qhov txawv ntawm magnification nrog wavelength yog hu ua chromatic sib txawv ntawm magnification, los yog lateral xim.
Dab tsi yog astigmatism aberration?
Astigmatism aberrations pom ntawm qhov chaw sab nraud ntawm qhov chaw saib hauv cov lo ntsiab muag tsis raug, thiab ua rau cov duab zoo tshaj plaws ncig (Airy pattern) plooj rau hauv lub voj voog, elliptical thaj, lossis kab, nyob ntawm qhov chaw ntawm lub dav hlau focal.
txhais tau li cas los ntawm kev sib txawv ntawm kheej kheej?
In thev naus laus zis ntawm kev yees duab: Aberrations. Spherical aberration yog tam sim no thaum lubsab nrauv ntawm ib lub lens tsis coj lub teeb rays mus rau tib lub hom phiaj raws li qhov nruab nrab. Cov duab tsim los ntawm lub lens ntawm apertures loj yog li ntawd tsis ntse tab sis tau ntse dua ntawm qhov apertures me.
