  In order to pre­serve the trans­verse beam emit­tance along the ac­cel­er­a­tion chain it is im­por­tant that the op­tics of the trans­fer lines is per­fectly matched to the op­tics of the rings. Spe­cial mon­i­tors ca­pa­ble of mea­sur­ing the beam pro­files with a turn by turn res­o­lu­tion are very help­ful in this re­spect. A new type of match­ing mon­i­tor has been de­vel­oped at CERN for the SPS and LHC ma­chines. This mon­i­tor re­lies on imag­ing OTR light by mean of a fast line scan CMOS and an asym­met­ric op­ti­cal sys­tem based on cylin­dri­cal lenses. This con­tri­bu­tion de­scribes the de­sign of this mon­i­tor, pre­sents the re­sults ob­tained dur­ing the 2012-13 run and out­lines the plans for fur­ther im­prov­ing the de­sign.
