L'OCT plein champ

“…de gallium indium (InGaAs) dont la réponse spectrale se situe entre 0,9 µm et 1,7 µm, des images d'OCT plein champ peuvent être acquises simultanément aux longueurs d'ondes centrales de 0,7 µm et 1,2 µm [15]. Avec une seule caméra InGaAs à réponse spectrale étendue dans le visible, nous avons démontré la possibilité d'acquérir des images dans 3 bandes spectrales centrées à 635 nm, 870 nm et 1170 nm [16].…”

Line-field confocal optical coherence tomography operating simultaneously at 800 nm and 1300 nm center wavelengths

“…However, spatial resolution also depends on the wavelength, resulting in a compromise between resolution and penetration. It is then interesting to work with two different spectral bands in order to benefit from the specific advantages of each band [15][16][17][18].…”

Full-Field Optical Coherence Tomography as a Diagnosis Tool: Recent Progress with Multimodal Imaging

“…Some FF-OCT multimodal systems have been reviewed in the recently published Handbook of Full-Field Optical Coherence Microscopy, edited by Arnaud Dubois [16]. We can non-exhaustively mention the multimodal combinations of FF-OCT with fluorescence [18], photothermal imaging [19], elastography [20], polarization [21], multispectral and hyperspectral imaging [22][23][24]. Most of these multimodal systems have been inspired by similar systems developed in standard OCT, but they needed to be adapted and redesigned to fit FF-OCT's particular configuration.…”
