Chapter 2Experimental setup and samplepreparationpastel-00527388, version 1 - 19 Oct 20102.1 Experimental setupThis work aims to study the photomechanical processes induced at nanoscale in thinfilms containing azo-polymers. In particular, we want to establish a correlation betweenthe light pattern and the resulting deformation. For this purpose we have developeda combined shear-force/SNOM microscope which allows to detect simultaneously, in(x, y, z)scan piezodither piezo(shear force)light collectionOPTICAL FIBERx,yzshear-forcedetectionphotomultiplicatorHT gainfeedbackPCz controlinputoptical fibertipzfilmsubstrate!yxTOPOGRAPHYIMAGEOPTICALIMAGElaser beamsFigure 2.1: Principle of the coupled measurement system.Computer(labview)23V C+-ezHT gain piezo 2G CR
