Fresnel Rhomb Retarders

Fresnel Rhomb Retarders e rata li-waveplates tsa Broadband tse fanang ka ho lieha ho lekana λ/4 kapa λ/2 ka holim'a mefuta e mengata e pharalletseng ea wavelengths ho feta kamoo ho ka khonehang ka li-waveplates tse birefringent.Li ka nka sebaka sa lipoleiti tsa ho lieha bakeng sa mehloli e mengata ea laser ea marang-rang, ea mela e mengata kapa e ka sebelisoang.

Rhomb e entsoe e le hore phetoho ea 45 ° phase e hlahe ka har'a ponahatso e 'ngoe le e' ngoe e ka hare e etsang hore ho be le ho lieha ho feletseng ha λ/4.Hobane phetoho ea mohato ke ts'ebetso ea ho hasana ha rhomb butle-butle, phetoho ea ho lieha ho fetoha le wavelength e tlase haholo ho feta mefuta e meng ea li-retarders.Half wave retarder e kopanya li-rhombs tse peli tsa kotara.
