1. An optical system comprising:

  • a pair of forward optical components each having a shutter for controlling the amount of transmission of a light from an object;

    an optical member for laying the optical axes of said pair of forward optical components one upon the other;

    a rearward optical component disposed so that the optical axis thereof may coincide with said optical axes laid one upon the other; and

    a stop disposed at or near a position whereat the optical axes of said pair of forward optical components intersect with each other;

    said optical system alternately varying the amounts of transmission of the light transmitted through the shutters of said pair of forward optical components to thereby time-serially form a parallax image.
