A flash ladar system has a laser provided with beam focusing optics for directing a laser fan beam pulse to a scanning element that in turn directs the laser fan beam to a vertical region of space. Light reflected from an object in the vertical region of space is directed by a reflecting element to a sensor provided with a column of photosensitive pixels that connects to a charge storage matrix of non-photosensitive pixels.
