Title
(EN) Bi-directional scanning system
Abstract
(EN) A bi-directional optical scanning system includes a spring-stiffened, taut-band mechanical subsystem that translates rotational motion of a servo-controlled actuator to translational (scan line or ' fast axis') motion of a sample relative to a stationary objective lens. A first taut steel band attaches to a first end of a shuttle that moves the sample over the fast axis. The band then wraps partially in one direction around a lightweight wheel that is rotated by the servo-controlled actuator. The second end of theband attaches to a pre-loaded spring that is, in turn, attached to the wheel. A second taut steel band wraps partially around the wheel in the opposite direction, with one end of the band attached to the wheel and the other end attached to a second end of the shuttle. When the wheel rotates in one direction, the shuttle moves forward, or backward in the other direction.
