In this study, we developed a swallowing measurement device using high-precision optical ranging sensors for the purpose of non-contact and low-constraint swallowing measurement. Specifically, we designed this device, and evaluated the ranging resolution, the evaluation of the linearity with respect to the ranging distance, and the examination of the swallowing state detection using a swallowing phantom. Details will be reported at the stage.
