OPTICAL UNIT AND IMAGING APPARATUS

摘要

An optical unit includes a condensing lens which condenses light from an object; a pupil splitting polarization separation element which separately outputs two linearly polarized light beams of which polarizing directions are different from the condensed light using a left eye polarization separation region and a right eye polarization separation region which are formed by having a pupil splitting line which is orthogonal to an optical axis as a border; a polarizing direction conversion element which converts polarizing directions of the two linearly polarized light beams which are output from the pupil splitting polarization separation element; and a rotation driving unit which rotates the pupil splitting polarization separation element and the polarizing direction conversion element in an optical axis rotational direction.
