Caabin milicsiga qalloocan ee ku jira isku-dhafka indhaha

Naqshadaha dahaadhka waxaa loo habeyn karaa heerarka hirarka gaarka ah sida3–5 μm (MWIR) or 8–12 μm (LWIR), iyo sidoo kale xargaha infrared-ka ee gaarka ah ee lagu qeexay shuruudaha nidaamka.

Naqshadeynta Indhaha iyo Dabacsanaanta Wax-soo-saarka Muraayadaha Si

Muraayadaha infrared-ka ee silikoon oo leh dahaarka IR AR ayaa laga heli karaa qaabab badan oo indhaha ah si ay u taageeraan naqshadaha kala duwan ee nidaamka:

Muraayadaha Plano-convex, plano-concave, bi-convex, iyo bi-concave muraayadaha
Joomatari wareegsan iyo mid gaar ah oo ku wareegsan
Dahaarka ka hortagga milicsiga IR ee hal dhinac ah ama laba-dhinac ah
Nadiifinta saxda ah ee sawirka dusha sare ee la xakameeyey iyo qallafsanaanta

Hawsha wax soo saarka si taxaddar leh ayaa loo xakameeyaa si loo hubiyo joogteynta dhererka diiradda, saxnaanta dusha sare, iyo waxqabadka dahaarka. Naqshadaha gaarka ah waxaa lagu taageeraa dhexroorka, dhumucda, qalooca, dulqaadka, iyo qeexitaannada dahaarka.

Meelaha Codsiga

Muraayadaha silikoon ee leh dahaarka IR-ka ee ka hortagga milicsiga ayaa badanaa loo isticmaalaa:

Nidaamyada sawir-qaadista kulaylka iyo aragtida infrared-ka
