A switchable optical system includes a primary optical system positioned to receive a forward view image, forward from the vehicle, during a reconnaissance mode of operation. A secondary optical system is operatively associated with the primary optical system for receiving opposing side images, side-looking from the vehicle. An imaging sensor is operatively associated with the primary optical system and with the secondary optical system. A mode switch is operatively associated with the primary optical system and the secondary optical system for switching between the reconnaissance mode of operation and a biomimetic mode of operation. The forward view image is sensed by the imaging sensor during the reconnaissance mode of operation; and, a portion of the forward view image and the opposing side images are simultaneously sensed by the imaging sensor for balancing the optic flow during the biomimetic mode of operation.
