Patent number: 9400161Abstract: An optical coherence tomography (OCT) probe using lead zirconate titanate (PZT). In the OCT probe using PZT, a sine wave is induced from a vibrator made of a piezoelectric element, so that an image in which the scanning range is increased can be captured due to the vibration of the vibrator. A decrease in the vibration of the vibrator can be minimized by optimizing the position where the base fixes the vibrator.Type: GrantFiled: August 8, 2012Date of Patent: July 26, 2016Assignee: Korea Institute of Industrial TechnologyInventors: Hyun Rok Cha, Dae Yeong Im, Jae Young Ahn, Hyoung Uk Nam, Tae Won Jeong
