I-Ghost Imaging System Isekelwe Ku-Spatial Light Modulator
Ukwaziswa Ngomkhiqizo
Uhlelo ngokuyinhloko luqukethe i-ghost imaging hardware device kanye ne-correlation computing software. I-SLM-based ghost imaging system ikakhulukazi isebenzisa i-SLM esikhundleni seshidi lengilazi yezinwele ezijikelezayo ukuze ithole inkambu yokukhanya ye-pseudo-thermal, esakazwa ngezindlela ezimbili ezihlukene zokukhanya, enye yazo iwuphawu lwesignali ngokusebenzisa into eqondiwe; enye ibizwa ngokuthi i-reference beam, esakazwa ngokukhululekile esikhaleni, bese itholwa yi-CCD ngokukhanya kwe-ghost imaging (noma ukubala kokulingisa kwethiyori); isofthiwe ihlobanisa ingqikithi yolwazi lwamandla okukhanya lwebhamu yesiginali kanye ne-reference beam, bese isithombe sento eqondiwe singakhiwa kabusha. Omunye ugongolo ubizwa ngokuthi i-reference beam, ngemuva kokusakazwa kwamahhala emkhathini, ukukhanya kokukhanya kutholwa yi-CCD - imaging yesipoki yendabuko (noma ukubala kwe-theoretical sekulingisa ukuthola - ukubala kokuhlakazeka kwezithombe); ngokusebenzisa isofthiwe kuzoba ugongolo lwesignali kanye nereferensi yolwazi lokuqina kokukhanya okuphelele kwezibalo zokuhlobana, ingakhiwa kabusha ukuze kutholwe isithombe sento eqondiwe.

Umsebenzi Wesistimu
● Traditional Ghost Imaging Module:i-atlas yenkambu yokukhanya okungezona eshisayo ingalingiswa futhi ilayishwe ku-SLM; izimpawu ze-APD detector kanye ne-CCD zitholwa ngokuvumelanisa okuhleliwe, futhi ekugcineni isithombe sento sibalwa nge-algorithm yokuhlanganisa.
● Ukubalwa kwemojula ye-ghost imaging:belingisa ukubalwa kwe-atlasi yenkundla yokukhanya okungelona-thermal futhi ilayishwe ku-SLM; ngokuvumelanisa okuhleliwe ukuze kutholwe umtshina we-APD kanye nokubalwa kwethiyori yesiginali yereferensi ye-atlas ehambisanayo, futhi ekugcineni ngokusebenzisa i-algorithm yokuhlanganisa ukuze kubalwe isithombe sento.
● Imojula yokulingisa ithiyori:isignali yereferensi nesignali yento ingalingiswa futhi ibalwe, bese isithombe sento singabalwa nge-algorithm ye-optical association.
