Abstract:
An optical system, comprising:a pair of front optical components; an optical member for superposing respective optical axes of said pair of front optical components on each other; a rear optical component disposed such that the superimposed optical axes coincide with an optical axis of said rear optical component, said rear optical component including a lens unit arranged to move during zooming, and a lens unit arranged to move during focusing and disposed on an object side of said lens unit arranged to move during zooming; and shutter means capable of independently controlling amounts of transmission of light fluxes respectively entering said pair of front optical components from an object, wherein said optical system forms parallactical images in a time-series manner by causing said shutter means to alternately change the amounts of transmission of light fluxes respectively entering said pair of front optical components from the object.
