Codsiga filtarrada ee qaybaha kala duwan ee spectral ee warshadaha indhaha

Codsiga filtarrada
Codsiga filtarrada ee qaybaha kala duwan ee qaybaha kala duwan ee warshadaha indhaha ayaa ugu horrayn ka faa'iidaysta awooddooda xulashada mawjadaha dhererka, taas oo u sahlaysa hawlqabadyo gaar ah iyaga oo habaynaya hirarka dhererka, xoojinta, iyo sifooyinka kale ee indhaha. Kuwa soo socdaa waxay muujinayaan kala-soocida aasaasiga ah iyo xaaladaha u dhigma:

Kala soocida ku salaysan sifooyinka muuqaalka:
1. Shaandheynta-dhaafka dheer (λ > dhererka mawjadda gooyay)
shaandhada noocan ahi waxa ay ogolaataa in mawjadaha dhererka ka dheer ee dhererka la jaray uu dhex maro iyada oo la xannibayo hirarka dhaadheer. Waxaa caadi ahaan loo isticmaalaa sawir-qaadista biomedical iyo bilicda caafimaadka. Tusaale ahaan, mikroskoobyada fluorescence waxay isticmaalaan filtarrada dhaafka dheer si ay u baabi'iyaan iftiinka mowjadaha gaaban ee soo dhexgala.

2. Shaandheynta-dhaafka gaaban (λ < dhererka mawjadaha gooyay)
Shaandheeyahani waxa uu gudbiyaa mowjadaha ka gaaban mawjadda la jaray oo waxa ay yaraynaysaa hirarka dhaadheer. Waxay codsiyo ka heshaa Raman spectroscopy iyo fiirsashada xiddigiska. Tusaalaha wax ku oolka ah waa IR650 filtarka gaaban, kaas oo ka shaqeeya nidaamyada ilaalinta amniga si loo xakameeyo faragelinta infrared inta lagu jiro saacadaha iftiinka.

3. Shaandheeyaha cidhiidhiga ah (bandwidth <10 nm)
filtarrada cidhiidhiga ah waxaa loo isticmaalaa in si sax ah loo ogaado meelaha sida LiDAR iyo Raman spectroscopy. Tusaale ahaan, shaandhada cidhiidhiga ah ee BP525 waxa ay leedahay mawjad dhexe oo dhererkeedu yahay 525 nm, ballac buuxa oo ah kala badh ugu badnaan (FWHM) oo keliya 30 nm, iyo gudbinta ugu sarreysa ee ka sarreysa 90%.

4. Shaandheeyaha shaandhada (xakamaynta xajinta <20 nm)
Shaandhooyinka caanka ah waxaa si gaar ah loogu talagalay in lagu xakameeyo faragelinta gudaha kala duwanaansho dhuuban. Waxay si ballaaran loogu dabaqaa ilaalinta laysarka iyo sawirka bioluminescence. Tusaalaha waxaa ka mid ah isticmaalka filtarrada shaandhada si loo xannibo qiiqa laysarka ee 532 nm ee keeni kara khataro.

Kala soocida ku salaysan sifooyinka shaqada:
- Filimada kala soocida
Qaybahan waxaa loo shaqeeyaa si loo kala saaro anisotropy crystal ama la yareeyo faragelinta iftiinka ambient. Tusaale ahaan, polarizers biraha birta ah waxay u adkeysan karaan shucaaca laysarka oo awood sare leh waxayna ku habboon yihiin in loo isticmaalo nidaamyada LiDAR wadista iskeed u madaxbannaan.

- muraayadaha Dichroic iyo kala-soocida midabka
Muraayadaha Dichroic waxay kala soocaan kooxo muuqaal ah oo gaar ah oo leh cidhifyada kala-guurka ee dhaadheer - tusaale ahaan, ka tarjumaya hirarka dhererka ka hooseeya 450 nm. Spectrophotometers saami ahaan waxay u qaybiyaan la kala qaado iyo iftiinka iftiimaya, shaqaynta inta badan lagu arkay nidaamyada sawir-qaadista badan.

Xaaladaha codsiga muhiimka ah:
- Qalabka caafimaadka: Daaweynta laysarka indhaha iyo aaladaha maqaarka waxay u baahan yihiin ciribtirka xadhkaha indhaha ee waxyeelada leh.
- Dareenka indhaha: Mikroskoobyada Fluorescence waxay shaqaaleeyaan filtarrada indhaha si ay u ogaadaan borotiinnada fluorescent ee gaarka ah, sida GFP, si kor loogu qaado saamiga-ilaa-qeylada.
- La socodka amniga: shaandhada IR-CUT waxay xannibaysaa shucaaca infrared inta lagu jiro hawlgalka maalintii si loo hubiyo in midabka saxda ah ee sawirada la qabtay.
Tiknoolajiyada Laser-ka: filtarrada loo yaqaan 'Noch filters' ayaa loo shaqeeyaa si loo xakameeyo faragelinta laysarka, iyadoo la adeegsanayo codsiyada nidaamyada difaaca militariga iyo aaladaha cabbirka saxda ah.
