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.
