:Wepresentinthispaperarevisionofthreedifferentmethodsweconceivedintheframework ofliquidcrystalonsilicon(LCoS)displayoptimizationandapplication.Wepreliminarilydemonstrate an LCoS self-calibration technique, from which we can perform a complete LCoS characterization. Inparticular,twoimportantcharacteristicsofLCoSdisplaysareretrievedbyusingself-addresseddigital holograms. On the one hand, we determine its phase-voltage curve by using the interference pattern generatedbyadigitaltwo-sectorialsplit-lensconfiguration. Ontheotherhand,theLCoSsurfaceprofileis alsodeterminedbyusingaself-addresseddynamicmicro-lensarraypattern. Second,theimplementation ofmicroparticlemanipulationthroughopticaltrapscreatedbyanLCoSdisplayisdemonstrated. Finally, anLCoSdisplaybasedinline(IL)holographicimagingsystemisdescribed. ByusingtheLCoSdisplayto implementadouble-sidebandfilterconfiguration,thisinlinearchitecturedemonstratestheadvantage ofobtainingdynamicholographicimagingofmicroparticlesindependentlyoftheirspatialpositionsby avoidingthenon-desiredconjugateimages.
