Abstract

The invention concerns a spectroscopy device (1) comprising: irradiation means (2, F1) for irradiating a biological sample (6) to be analyzed; and measuring means (FM) for measuring a light intensity retransmitted by respective measured zones of said biological sample. The invention is characterized in that it comprises reinjecting means (F2) for capturing a light intensity retransmitted by a recovery zone of said biological sample, and for reinjecting said captured light intensity on a zone for reinjecting (Si) said biological sample.
