    摘要： The object of the invention is to provide a method and a device for characterizing microscopic elements, which is both reliable and inexpensive and which gives good results when there is a large number of elements to be characterized. For this purpose, the invention proposes chopping the source signal (12, 120) by means of MOEMS microsystems (200) based on optoelectromechanical elements (220), thereby generating novel options for the modulation, especially temporal modulation, of excitation signals. More precisely, one subject of the invention is a method of characterizing microscopic elements consisting in particular in propagating a dispersed lamp source signal (12, 120), in spatially chopping the spectrum of the source signal (12, 120) into at least two excitation signals (18, 180) having predetermined wavelengths λi, in encoding the excitation signals (18, 180), in focusing the excitation signals (18, 180), so as to generate a probe signal (28, 280) propagated towards a measurement zone (30, 300), and in analyzing an interaction signal (32, 320) deriving from the interaction of the probe signal (28, 280) with the microscopic elements that are located in the measurement space (30, 300). The spatial chopping of the light source signal spectrum is carried out by a MOEMS microsystem (200) based on optoelectromechanical elements (220).

    摘要： According to one aspect, the invention relates to a laser emission device for the spectroscopic analysis of a sample, comprising: a primary laser source (401) emitting a pump beam (I
    5 ) and an excitation beam (I
    2 ), said two beams being pulsed and having a nanosecond or subnanosecond pulse time; a non-linear optical fibre (406) into which the excitation beam is injected in order to form a probe beam (I
    4 ) having a wide spectral band; a device (405) for controlling the time profile of either the pump beam or the excitation beam, allowing compensation of the time spreading of the probe beam generated by the non-linear optical fibre, in order to obtain pump and probe beams having similar pulse times; and means (409) for spatially overlaying of the pump and probe beams for the spectroscopic analysis of the sample.
