Amfani da kalaman Properties na haske. diffraction grating

A kalaman yanayin haske, an riga an tabbatar da na dogon lokaci. Don shirya m matsaloli sau da yawa amfani da ka'idojin lissafi kimiyyan gani da hasken wuta, amma kalaman Properties na haske ne sosai yadu amfani a fannoni daban daban na zamani da kimiyya da fasaha. Wani misali na wannan shi ne wani diffraction. Da ikon da kalaman tanƙwara a kusa da cikas ci karo a cikin hanyar Allah, kuma halin da haske. Wannan abu ya faru a lokacin da taguwar ruwa fada cikin ikon yinsa, daga abin da ake kira na lissafi inuwa. A bayani na sabon abu na diffraction ba Huygens 'manufa. A cewar wannan bayani, kowane batu a kan hanyar da kalaman da samun up, ta zama cibiyar ga sakandare tãguwar ruwa. A ambulan na wadannan taguwar ruwa da aka ba wavefront matsayi na kowace m batu a lokacin.

A misali wani jirgin saman kalaman kullum faru a kan wani rami sanya a cikin wani opaque allo, ka'idar Huygens, kowane batu na wanda aka kasaftawa wani bude rabo daga wavefront, muhimmi ikon zama tushen sakandare taguwar ruwa (a wata kama isotropic matsakaici ne mai siffar zobe).

Yana isa ga shirya da ambulan na sakandare tãguwar ruwa a wani lokaci, da kuma saukin gano sabon abu na diffraction kalaman gefen rami. Wannan shi ne saboda gaskiyar cewa wavefront shiga cikin yankin da ake kira geometrical inuwa.

Amfani diffraction kaddarorin da aka yi amfani da ko'ina a cikin na'ura, ya kira wani diffraction grating. A cikin farko gwaje-gwajen shafe da diffraction haske Dzheyms Gregori amfani da saba gashin tsuntsu. Bisani, ya aka maye gurbinsu da wani takamaiman Tantancewar na'urar. A diffraction grating aka buga a farfajiya na wani sa na wani gagarumin yawan Lines shirya kai a kai. Suna iya zama kamar yadda ramummuka da tsinkaya, dangane da nau'in abin da kankare grating.

Akwai iri biyu lattices - na nuna da kuma m. Na farko da kungiyar hada da na'urorin da suke amfani da wani na nuna surface da aiyuka shanyewar jiki. Na biyu m surface amfani da nan za a iya amfani da a matsayin kammala shãfe, kuma tsaguwa.

The aiki manufa na diffraction grating kai tsaye a sakamakon kalaman Properties na haske. Don warware haske kalaman gaban grille amfani da shanyewar jiki. A sakamakon haka, kafa da ake kira mutum bim na jiwuwa haske. Jurewa diffraction da touch, suka tsoma baki tare da juna. Ganin cewa daban-daban wavelengths na tsangwama Maxima ƙirƙirar gaba daya da kusurwoyi mabambanta (m hanya bambancin da tsoma baki bim), samu a fitarwa bazu cikin wani bakan na fari haske.

A diffraction grating aka yi amfani a matsayin na'urar a fannoni daban daban na mutum aiki. Ana amfani da a spectroscopic kida da kuma yadda na gani na'urori masu auna sigina na kusurwa (mikakke) motsi da kuma yadda polarizers ko infrared tacewa. Har ila yau, yana iya zama da katako splitter ga interferometers ko gilashi "anti-na nuna" da maki.

Akwai diffraction grating for X-haskoki. Create shi juya a kira su a zahiri ba zai yiwu ba aiki. Don warware wannan matsala, masana kimiyya sun tafi asali hanya. Domin cikin bazuwar na X-haskoki amfani crystal lattices na wasu lu'ulu'u.

Kamar yadda wani babban halayyar aka dauke ƙuduri diffraction grating. Yana wakiltar jimlar yawan Lines a layin wutar lantarki, wanda aka yawaita da oda na matsakaicin masaƙa. Wannan magana za a iya rubuta more matsayin tabbatarwa cewa bambancin dake tsakanin mita halayyar daidaita da juna na bambanci tsakanin lokacin jinkiri na nassi mafi muni, wãtau haskoki, da ake kira tsoma baki.

A rayuwar yau da kullum mai kyau misali da diffraction grating iya zama a matsayin m faifai ko platter. Amma ga yi na masana'antu kayan aiki amfani high-tech kayan aiki da high ainihin.
