摘要:
Arranged within a measuring-light generating unit of an endoscope apparatus for three dimensional measurement, according to the invention, are measuring means, a lamp for outgoing a normal illuminating light, and a laser for outgoing a measuring light. Connected to the measuring means is a signal line which is connected to a CCD. Further, an illuminating light outgone from the lamp is condensed by a condenser lens, and is incident upon an incident end surface of a light guide. Furthermore, the measuring light outgone from the laser is condensed by the condensing lens, and is incident upon the incident end surface of the image guide. Moreover, the incident end of the image guide is connected to scanning means formed by a piezo-electric element, a speaker (voice coil) or the like through a connecting element. The scanning means is operated whereby the incident end of the image guide is reciprocally moved in a direction perpendicular to an optical axis of the measuring light. The measuring light is a light having extension or spreading. However, a flux of light of the measuring light is extremely thin, and a spot light having minimum resolution that is a single glass fiber forming the image guide is projected onto the subject.
