<p>An image pickup head for an image pickup device capable of permitting the observed section at a subject (6) to be illuminated with a uniform lumination while preventing the reflection of light at the observed section from adversely affecting an image of the observed section. A first polarizing element (9) having a predetermined polarization plane is arranged in the optical path of light projected from the projection end of a light guide (4) onto a subject, while a second polarizing element (12) having a predetermined polarization plane is arranged in the optical path of light reflected at the subject and guided to an image pickup element (3). The polarization planes of the first and second polarizing elements (9, 12) are varied relative to each other to provide an image either including or free of light reflected at the surface of the subject.</p> |
