Abstract
An optical scanner device, comprising a scanning unit, which casts irradiation light emitted from a light source in an arbitrary direction to scan an observation object, an objective lens system, which converges the irradiation light on the observation object, and a photo-detector unit, which is disposed on an optical axis of the objective lens system to have the irradiation light transmit therethrough, is provided. A position of the irradiation light converged on the observation object is detected based on a position of a light spot of the irradiation light transmitting through the photo-detector unit.

An optical scanner device, comprising:
- a scanning unit, which casts irradiation light emitted from a light source in an arbitrary direction to scan an observation object;
- an objective lens system, which converges the irradiation light on the observation object;
- and
- a photo-detector unit, which is disposed on an optical axis of the objective lens system to have the irradiation light transmit therethrough,
- wherein a position of the irradiation light converged on the observation object is detected based on a position of a light spot of the irradiation light transmitting through the photo-detector unit.
A light spot position detector unit, comprising:
- an objective lens system, which converges irradiation light emitted from a light source on an observation object;
