Hur fungerar teleskopet? Uppfinningen av teleskop

Teleskopet är en mycket imponerande verktyg som visar mycket avlägsna objekt som om de var nära oss. Teleskop används numera i olika storlekar. Förutom de små teleskop som du kan plocka upp från leksaksaffären, finns det sorter som rymdteleskopet Hubble, som har massor av vikt. Om du vill prova på vad en imponerande enhet teleskopet är, kan du läsa en handskrift på 80 meter bort med en liten 20cm teleskop.

 

Det finns två typer av teleskop i världen. Reflekterande teleskop med objektivets glas och spegel-linssystemet. Även om arbetet med båda metoderna är samma, arbetar de på mycket olika sätt.

 

För att förstå hur teleskopet fungerar, du måste tänka, varför kan vi läsa i artikel 80 meter bort? Svaret är väldigt enkelt eftersom storleken på incription på vår näthinna är fortfarande mycket små och oläslig. Om vi betraktar våra ögon som en digitalkamera, kan vi se att texten på 80 meter från hela bilden kommer att bestå av flera pixlar och är ganska långt från storleken som kan läsa. Om vi hade en mycket större öga, kunde då vi fokusera på den del av bilden och Läs artikeln.

 

Det är vad teleskopets arbetande logik är liksom. Ljuset som kommer från objektivets fokus samlas någon gång bryta eller reflekterande med speglar och det är följde att det ser mycket mer. Linsen är fast i det mänskliga ögat, så vi inte kan zooma in eller ut. Vad vi kan göra är att bara fokusera på en punkt.

 

När vi tar ett förstoringsglas i din hand, skapa vi faktiskt ett teleskop system mellan förstoringslinsen och vår egen ögats lins.


 

Här reflekteras ljuset från linsen i ögat objektivet och bilden förstoras nu som det inträffar i små linsen.

 

Teleskop har två grundläggande funktioner, först är hur väl det blir ljuset, och den senare vet hur mycket bilden tar. Dessa också beror på renhet, kvalitet, ojämnheter och de flesta viktigare storlek lins linser. Den Langer objektivet används, ju större bilden erhålls.

 

Historia

Teleskopet var första inventered av holländska Hans Lippershey 1608 och används i militär rymdfart. Baserat på principen om refraktion, är detta teleskop först att använda i astronomi. De använde teleskop som består av en kombination av lippershey och Galileo konvex och conccave linser. 1611 började Kepler använda teleskopet utvecklas med hjälp av två konvexa linser. Teleskop med detta system som utvecklats av Kepler är fortfarande bäst.
