Abstract

A spectrophotometer (1), in particular for the spectral analysis of a source (5), comprising a Fabry-Perot resonator (2) including a partially transparent entry mirror (7) suitable for being crossed by radiation originating from the source (5), and a partially transparent output mirror (8). The spectrophotometer (1) also comprises a modulator (9) suitable for modulating the optical path of the radiation between mirrors (7, 8) and a photosensor matrix (3) arranged downstream of the exit mirror (8) of the Fabry-Perot resonator (2). The photosensors (3) are suitable to supply electrical signals representative of a function which correlates the intensity (I) of the radiation emerging from the Fabry-Perot resonator (2) with the length of the optical path (d) between the mirrors (7, 8) thereof. The spectrophotometer (1) finally also includes a processing and control unit (4) connected to the photosensor matrix (3) and arranged to generate data representative of the emission spectrum of the source.
