Abstract:
1. A method of characterizing microscopic elements comprising: propagating a dispersed light source signal, spatially chopping the spectrum of the source signal into at least two excitation signals having predetermined wavelengths λ coding the excitation signals, focusing the excitation signals in order to generate a sensor signal propagated towards a measuring space; analyzing an interaction signal issuing from the interaction of the sensor signal with the microscopic elements situated in the measuring space; and wherein the spatial chopping of the spectrum of the source signal is carried out by a microsystem of elements with opto-electromechanical elements and the step of chopping the excitation signals is preceded by a phase of selecting the spectral width of these excitation signals, wherein the opto-electromechanical elements are of a cantilever type, are substantially triangular in shape and are disposed along first and second longitudinally and transversely adjustable bars placed side by side such that the opto-electromechanical elements of the first bar are embedded in the opto-electromechanical elements of the second bar.
