Abstract
(EN)
An optical system for adjusting a proportion of light of a particular spectral band that is emitted from the optical system. A dichroic mirror is configured to reflect light of a first spectral band from a light source towards a distal end of an optical fiber while allowing light of a second spectral band to pass through the dichroic mirror. The second mirror is positioned behind the dichroic mirror and is configured to reflect light of the second spectral band. A mirror actuator is coupled to the second mirror and is configured to adjust a proportion of the light of the second spectral band that is emitted by the optical system by adjusting a position of the second mirror relative to the dichroic mirror.
(FR)
L'invention concerne un système optique pour ajuster une proportion de lumière d'une bande spectrale particulière qui est émise à partir du système optique. Un miroir dichroïque est configuré pour réfléchir une lumière d'une première bande spectrale, d'une source de lumière vers une extrémité distale d'une fibre optique, tout en permettant à une lumière d'une seconde bande spectrale de traverser le miroir dichroïque. Le second miroir est positionné derrière le miroir dichroïque et est configuré pour réfléchir une lumière de la seconde bande spectrale. Un actionneur de miroir est couplé au second miroir et est configuré pour ajuster une proportion de la lumière de la seconde bande spectrale qui est émise par le système optique par l'ajustement d'une position du second miroir par rapport au miroir dichroïque.
