Isistimu yokulingisa ye-Atmospheric Turbulence Based on Spatial Light Modulator
Ukwaziswa Ngomkhiqizo
I-Atmospheric turbulence i-eddi yomumo nosayizi ongahleliwe. Emkhakheni we-Optics, ibhekisela ekushintsheni okungahleliwe kwenkomba ye-refractive okulethwa ukushintsha okungahleliwe kwezinga lokushisa lendawo kanye nokucindezela emkhathini, okwenza kube nzima ukubamba uguquko lwesiyaluyalu ngesikhathi esifanele ngenxa yoshintsho kanye nomthelela wezici ezingaqinisekile ezifana nezinga lokushisa nokucindezela.
Isistimu yokulingisa i-atmospheric turbulence esekelwe ku-SLM ikakhulukazi yakhiwe isofthiwe ye-algorithm yesikrini sesigaba kanye nemojula yokulingisa i-turbulence, lapho isofthiwe ye-algorithm yesikrini sesigaba ikakhulukazi ibala futhi ikhiqize isikrini sesigaba se-atmospheric turbulence; imojula yokulingisa isiphithiphithi isekelwe ikakhulukazi ohlelweni lokudlulisa amehlo nokutholwa kwe-SLM. Uhlelo lusebenzisa ukulingiswa kwezinombolo ukuze kukhiqizwe isikrini sesigaba futhi kusilayishe kumoduli, esebenzisa amandla esigaba sokumodula kwe-SLM ukuze kukhiqizwe ukuhlanekezela kwesigaba ensikeni yesigameko, ukuze kuzuzwe umphumela wokulingisa ukuxokozela komkhathi elabhorethri.
Amapharamitha womkhiqizo
| Umthombo Wokukhanya | 532nm noma 1550nm lasers |
| Ukunemba kwesigaba sokulingisa | 1/8m |
| Ububanzi obulingiswa be-analog (Isistimu yokuhlola 1m) | Umthelela wesiyaluyalu ebangeni langempela le-1km-10km ungalingiswa |
