Advances in Optomechanical Scanning Technologies for High-End Biomedical Applications

Conference paper
Part of the Mechanisms and Machine Science book series (Mechan. Machine Science, volume 18)


The paper presents an overview of our main contributions on optomechanical scanners used especially for biomedical applications with high requirements—with a focus on Optical Coherence Tomography (OCT). Rotating polygon scanners (pyramidal or prismatic, normal or inverted) are approached, in their kinematic, kinetostatic and dynamic aspects—with requirements of OCT systems. Oscillatory, galvanometer-based scanners are approached in their optomechanical aspects, with a focus on their dynamical aspects. Their optimal scanning functions were demonstrated—to produce the highest duty cycle (i.e., time efficiency) of the device: linear on the active portions with parabolic non-linear stop-and-turn portions. This result contradicts what was previously considered in the literature, that linear plus sinusoidal scanning functions were optimal. 2D (bi-dimensional) scanning systems with Risley prisms on which we are currently working are also pointed out.
