Smart control of light propagation through highly scattering media is a much desired goal with major technological implications.Since interaction results in partial or complete depletion ballistic photons, it principle impossible to transmit images distances longer than the extinction length.Nevertheless, different methods for image transmission, focusing, and imaging by means wavefront have been published over past few years.In this paper we show that single-pixel optical systems, based on compressive detection, can also overcome fundamental limitation imposed multiple successfully information.But, contrast recently introduced schemes use transmission matrix technique, our approach does not require any a-priori calibration process ultimately makes present method suitable dynamic media.This represents an advantage previous rely feedback control, especially short speckle decorrelation times.
