a) Usoro atụmatụ

Usoro ntule tumadi na-eme atụmatụ omimi nke mmebi nke sub-elu dị ka nha nha nke ihe abrasive si dị na nha elu nke ihe ahụ.Ndị na-eme nchọpụta na-eji ọnụ ọgụgụ dị ukwuu nke ule iji guzobe mmekọrịta kwekọrọ n'etiti nha nha nke ihe abrasive na omimi nke mmebi nke sub-surface, yana tebụl kwekọrọ n'etiti nha nke ihe na-adịghị mma nke akụkụ ahụ na sub-. mmebi elu.Enwere ike ime atụmatụ mmebi nke dị n'okpuru ala nke elu ihe dị ugbu a site na iji akwụkwọ ozi ha.

b) Tomography nke jikọrọ anya (OCT)

Tomography njikọ anya, ụkpụrụ bụ isi nke ya bụ nnyonye anya Michelson, na-enyocha ozi a tụrụ site na nrịbama nnyonye anya nke ọkụ abụọ.A na-ejikarị usoro a na-elele anụ ahụ dị ndụ ma na-enye tomography nke akụkụ dị n'okpuru ala nke anụ ahụ.Mgbe a na-eji usoro OCT hụ mmebi nke ala dị n'okpuru ala nke elu anya, a ga-atụlerịrị ihe nrịbama index nke ihe atụ tụrụ iji nweta omimi mgbape n'ezie.Enwere ike ịkọ usoro a na-achọpụta ntụpọ na omimi nke 500μm yana mkpebi kwụ ọtọ karịa 20μm.Otú ọ dị, mgbe a na-eji ya maka nchọpụta SSD nke ngwa anya, ìhè na-egosipụta site na oyi akwa SSD adịghị ike, ya mere ọ na-esiri ike ịmepụta nnyonye anya.Na mgbakwunye, ịgbasa n'elu ga-emetụtakwa nsonaazụ nha, na nha nha kwesịrị ka emeziwanye ya.

c) Usoro ịgbasa laser

A na-amụkwa nke ọma n'ọgba aghara laser n'elu elu fotometric, na-eji ihe ndị na-agbasasị nke laser iji chọpụta oke mmebi nke dị n'okpuru ala.Ndị a na-ahụkarị gụnyere mkpokọta ntughari microscopy (TIRM), microscopy confocal laser scanning (CLSM), na intersecting polarization confocal microscopy (CPCM).cross-polarization confocal microscopy, wdg.

d) Na-enyocha microscope acoustic

Nyocha acoustic microscopy (SAM), dị ka usoro nchọpụta ultrasonic, bụ usoro nnwale na-adịghị emebi emebi nke a na-ejikarị achọpụta ntụpọ dị n'ime.A na-ejikarị usoro a tụọ ihe nlele na elu dị larịị.Mgbe elu nke ihe nlele ahụ siri ike, a ga-ebelata nha nha n'ihi mmetụta nke ebili mmiri gbasasịrị n'elu.
