 \section{Introduction}
 
+Cantilevers  are  used  inside  atomic  force  microscope  which  provides  high
+resolution images of  surfaces.  Several technics have been  used to measure the
+displacement  of cantilevers  in litterature.   For example,  it is  possible to
+determine  accurately   the  deflection  with   optic  interferometer~\cite{CantiOptic89},
+pizeoresistor~\cite{CantiPiezzo01}                 or                 capacitive
+sensing~\cite{CantiCapacitive03}.
