Title (EN) AGILE IMAGING SYSTEM
(FR) SYSTÈME D'IMAGERIE SOUPLE
Abstract:
(EN) An agile optical imaging system for optical coherence tomography imaging using a tunable source comprising a wavelength tunable VCL laser is disclosed. The tunable source has long coherence length and is capable of high sweep repetition rate, as well as changing the sweep trajectory, sweep speed, sweep repetition rate, sweep linearity, and emission wavelength range on the fly to support multiple modes of OCT imaging. The imaging system also offers new enhanced dynamic range imaging capability for accommodating bright reflections. Multiscale imaging capability allows measurement over orders of magnitude dimensional scales. The imaging system and methods for generating the waveforms to drive the tunable laser in flexible and agile modes of operation are also described.
(FR) L'invention concerne un système d'imagerie optique souple qui permet d'effectuer une tomographie par cohérence optique à l'aide d'une source accordable comportant un laser VCL à longueur d'onde accordable. La source accordable, qui présente une longueur de cohérence importante, est apte à fournir un taux de répétition de balayage élevé et de modifier à la volée le trajet de balayage, la vitesse de balayage, le taux de répétition de balayage, la linéarité de balayage, ainsi que la plage d'émission en longueur d'onde, afin de prendre en charge plusieurs modes d'imagerie OCT. Le système d'imagerie offre également une nouvelle capacité d'imagerie à plage dynamique améliorée afin de recevoir les réflexions lumineuses. La capacité d'imagerie à plusieurs échelles permet d'effectuer des mesures sur des ordres de grandeur des échelles. L'invention concerne également le système d'imagerie et les procédés de génération des formes d'ondes afin d'exciter le laser accordable en modes de fonctionnement flexible et souple.
