Chogulitsa chokhala ndi mapangidwe atsopano chimakhala ndi kubwereza kwabwino komanso ma frequency osinthika, omwe amapambana malire ndi kusowa kwa nyali zachikhalidwe za Xenon.Zimatsimikizira kuti mphamvu yowoneka bwino yosakhudzidwa ndi mafupipafupi olimbikitsa ndipo imakhala ndi nyali za monochromatic (zofiira, zobiriwira, zabuluu, zachikasu) zomwe zimakhudzidwa ndi dongosolo lowala ndi lakuda la retina.
Mbiri yatsatanetsatane
Makhalidwe:
· Gwero la kuwala kwa stimulator yowala ndi LED, yomwe ili ndi izi:
Kuchuluka kwa kunyezimira ndi mitundu yosiyanasiyana (mwachitsanzo yoyera, yofiira, yobiriwira, yabuluu ndi yachikasu) pamaziko a tricolor.
Kubwereza kwabwino kumatsimikizira kuti mphamvu ya flash sidzakhudzidwa ndi mafupipafupi ndikupereka kusonkhezera kowoneka bwino mpaka 50 Hz.
Popanda gwero lililonse lowopsa (ray infrared, UV).Wavelength imayendetsedwa mosamalitsa ndipo imatha kuperekedwa malinga ndi zomwe kasitomala akufuna.
Kugunda kwamtundu wa 2-3s ndi kuzindikira kwa C wave.
Kuwala kolondola kumapereka zotsatira zodalirika za matenda.
· Anti-jamming.
· Makina okhazikika amakina amatsimikizira zotsatira zowunikira komanso zenizeni.
· Mapulogalamu owunikira amphamvu komanso njira yabwino yofunsira milandu.
· Chotsani zokha zachinyengo.
· Kulumikizana kwadongosolo koyenera.
· Kompyuta yochititsa chidwi ndi zida zina zimalumikizidwa ndi waya wa USB.
·Zopangidwa kuti zigwirizane ndi miyezo yapadziko lonse lapansi.
Ntchito zazikulu:
F-ERG, EOG, P-ERG, P-VEP, F-VEP, kusanthula VEP ndi ERG yapawiri ya kuwala.
Ntchito yachipatala
Mankhwalawa amagwiritsidwa ntchito popereka maziko oyenera a matenda osiyanasiyana: mwachitsanzo, matenda a fundus, glaucoma, amblyopia, ndi chotchinga chamtundu, polemba komanso kufotokozera mitengoyo.
