Abstract
A switch-type imaging fiber apparatus and a branch-type imaging fiber apparatus are provided. Light emitted from a laser light source is made incident on an opening of an IF (image fiber) guided by a GM (galvanometer), output from an optical system provided at a leading end portion of the IF, and applied to an observation target. The light reflected by the observation target is sent back to the IF, transformed into parallel light by an fθ objective lens, reflected by a dichroic mirror, made incident on an image pickup device (CCD) via an imaging lens, and can be observed on a monitor. The GM is controlled to switch to make the light incident on the opening of an arbitrary one of a plurality of IFs. Accordingly, observation can be performed by focusing the light solely on the arbitrary IF.
