1. A two-parallel-channel reflector (TPCR) with focal length and disparity control, assembled to an imaging device, so that the imaging device is capable of synchronously capturing a left side view image and a right side view image of a scene, the TPCR comprising:

  • a left side imaging channel constructed by a left side image inlet, a left side outward reflecting unit formed by a curved reflecting mirror, and a left side inward reflecting unit formed by a curved reflecting mirror, wherein an end of the left side imaging channel is connected to a central image inlet; and

    a right side imaging channel constructed by a right side image inlet, a right side outward reflecting unit formed by a curved reflecting mirror, and a right side inward reflecting unit formed by a curved reflecting mirror, wherein an end of the right side imaging channel is connected to the central image inlet;

    the left side and the right side imaging channels being configured whereby the left side view image enters from the left side image inlet, reaches the left side outward reflecting unit, is parallelly reflected to the left side inward reflecting unit, is reflected by the left side inward reflecting unit, and enters the imaging device from the central image inlet, the right side view image enters from the right side image inlet, reaches the right side outward reflecting unit, is parallelly reflected to the right side inward reflecting unit, is reflected by the right side inward reflecting unit, and enters the imaging device from the central image inlet;

    further wherein a parallel reflecting path is defined for each of the left side view and right side view images reflected from the left side and right side outward reflecting units to the left side and right side inward reflecting units.
