OPTICAL SCANNING OBSERVATION APPARATUS

摘要

An optical scanning observation apparatus includes a light emission timing controller, a fiber, a driver, a photodetector, an offset processor that corrects an offset value based on an electrical signal output by the photodetector while a light emission timing controller suspends light emission of a light source, and a signal processor that generates an image signal based on the electrical signal for which the offset value was corrected by the offset processor.

1. An optical scanning observation apparatus for scanning an object with illumination light from a light source and acquiring an image of the object, the optical scanning observation apparatus comprising:
a light emission timing controller configured to control a light emission timing of the light source; a fiber configured to guide the illumination light from the light source and emit the illumination light toward the object from a tip of the fiber, the tip being supported to allow oscillation; a driver configured to drive the tip of the fiber by vibration; a photodetector configured to detect detection light obtained from the object and convert the detection light obtained from the object to an electrical signal; an offset processor configured to correct an offset value based on the electrical signal output by the photodetector while the light emission timing controller suspends light emission of the light source; and a signal processor configured to generate an image signal based on the electrical signal for which the offset value was corrected by the offset processor.
