SCANNING ENDOSCOPE SYSTEM AND METHOD OF OPERATION OF SCANNING ENDOSCOPE SYSTEM

摘要

A scanning endoscope system includes: a fiber that guides illuminating light from a light source; a first actuator provided on a side of the fiber and expands/contracts according to an applied voltage, thereby swinging the fiber; a second actuator disposed at a position facing the first actuator across the fiber and expands/contracts according to an applied voltage, thereby swinging the fiber; a drive signal output section applying a first voltage for setting a reference position of the fiber where the first actuator is in a contracted state, to the first actuator, and applying a second voltage for setting the reference position of the fiber where the second actuator is in a contracted state, to the second actuator; and a controller that in order to change the reference position of the fiber, controls the drive signal output section to change at least one of the first voltage and the second voltage.

1. A scanning endoscope system comprising:
a fiber that guides illuminating light emitted from a light source; a first actuator provided on a side of the fiber, the first actuator expanding/contracting according to an applied voltage, thereby swinging the fiber; a second actuator disposed at a position facing the first actuator across the fiber, the second actuator expanding/contracting according to an applied voltage, thereby swinging the fiber; a drive signal output section that applies a first voltage value for setting a reference position of the fiber where the first actuator is in a contracted state, to the first actuator, and applies a second voltage value for setting the reference position of the fiber where the second actuator is in a contracted state, to the second actuator; and a controller that in order to change the reference position of the fiber, controls the drive signal output section to change at least one of the first voltage value and the second voltage value.
