PROBLEM TO BE SOLVED: To provide an optical unit and an imaging apparatus capable of presenting stereoscopic images without giving any discomfort feeling to a viewer without rotating an imaging element even when the positional direction of the viewer changes with respect to the object.SOLUTION: The optical unit includes: a collecting lens for collecting a beam of light coming from a subject; a pupil division polarization separation element that separates the collected light into two kinds of linear polarization, each of which has a different polarization direction in a left-eye polarization separation area and in a right-eye polarization separation area which are formed at both sides of a pupil division line as the interface crossing perpendicularly to the optical axis and outputs the same therefrom; a polarization direction conversion element that converts the polarized direction of the two kinds of linear polarization output from the pupil division polarization separation element; and a rotation drive section that rotates the pupil division polarization separation element and the polarization direction conversion element according to an instruction. |
