Abstract
We developed a laryngoscope with an integrated OCT beam path for office-based non-contact imaging of human vocal folds. In combination with conventional videolaryngoscopy superficial and subsurface lesions can be detected. For error-free interpretation of OCT images obtained in office-based examination motion artifacts have to be considered. To demonstrate the implications on OCT images we simulated probe and patient movements for different commercial systems representing the three OCT modalities and analyzed the OCT data. Our results show that time domain and fourier domain OCT with a swept light source are probably better suited for noncontact imaging of awake patients than the current generation of fourier domain OCT engines with spectrometer design.
