Kumvetsetsa Laser Imager Resolution: Buku Lathunthu

Zithunzi za laser akudziwika kwambiri m'magawo osiyanasiyana, kuphatikizapo kujambula kwachipatala, kujambula kwa zinyama, ndi ntchito za mafakitale. Chimodzi mwazinthu zofunika kuziganizira posankha chojambula cha laser ndikusintha kwake. Mu positi iyi yabulogu, tipereka chiwongolero chokwanira kuti timvetsetse kusamvana kwa zithunzi za laser komanso momwe zimakhudzira mtundu wazithunzi.

Kufotokozera Kusamvana

Resolution imatanthawuza kuthekera kwa chojambula cha laser kujambula ndi kutulutsanso bwino pachithunzichi. Nthawi zambiri amayezedwa ndi ma pixel pa inchi (PPI) kapena madontho pa inchi (DPI). Chiwonetserocho chikakwera, m'pamenenso wojambula zithunzi amatha kujambula ma pixel ambiri kapena madontho pa inchi imodzi, zomwe zimapangitsa kuti chithunzicho chikhale chakuthwa komanso chatsatanetsatane.

Zomwe Zimakhudza Kusamvana

Zinthu zingapo zimakhudza kusintha kwa chithunzi cha laser:

Kukula kwa Sensor: Kukula kwa sensa ya chithunzicho kumagwira ntchito yofunika kwambiri pakuzindikira kusamvana. Sensa yokulirapo imatha kujambula ma pixel ambiri, zomwe zimatsogolera kuzithunzi zapamwamba.

Kachulukidwe ka Pixel: Kachulukidwe ka Pixel kumatanthauza kuchuluka kwa ma pixel omwe amapakidwa m'dera lopatsidwa la sensor. Kuchulukira kwa pixel nthawi zambiri kumatanthawuza kusamvana kwakukulu.

Ubwino wa Lens: Ubwino wa disolo la wojambula umakhudzanso kusamvana. Magalasi apamwamba kwambiri amatha kujambula zithunzi zakuthwa, zatsatanetsatane, pomwe disolo lapamwamba kwambiri limatha kuwonetsa kusawoneka bwino kapena kupotoza.

Impact of Resolution on Image Quality

Kukhazikika kumatenga gawo lalikulu pazithunzi zonse zomwe zimapangidwa ndi chojambula cha laser. Zithunzi zowoneka bwino kwambiri ndi zakuthwa, zatsatanetsatane, komanso zoyenera kugwiritsa ntchito zomwe ndizofunikira kwambiri, monga kuzindikira zachipatala kapena kuwunika kwa mafakitale.

Kusankha Kusankha Bwino

Kusankha koyenera kwa chojambula cha laser kumadalira ntchito yake. Pakujambula kwachipatala, kusankha kwa 300 PPI kumalimbikitsidwa nthawi zambiri. Pakujambula kwa Chowona Zanyama, kukonza kwa 200-300 PPI kungakhale kokwanira. Kwa ntchito zamafakitale, kusamvana kofunikira kumatha kusiyanasiyana kutengera ntchito inayake.

Kusintha kwa laser imager ndichinthu chofunikira kwambiri chomwe muyenera kuganizira posankha chojambula pazosowa zanu. Pomvetsetsa zinthu zomwe zimakhudza kukonza ndi momwe zimakhudzira mtundu wazithunzi, mutha kupanga chisankho mwanzeru chomwe chikugwirizana ndi zomwe mukufuna.
