An object designator system has a laser light source, and image sensor, a display, and a processor coupled with a non-transitory processor-readable medium storing processor-executable code. The image sensor captures an external scene image. The processor determines a range to an object of interest in the external scene and an exposure delay based on the range. The laser light source emits a laser light pulse into the external scene. The image sensor, based on the exposure delay, captures a laser spot image including laser light pulse reflections, and a spot baseline image of the external scene. The processor determines, based on the laser spot image and the spot baseline image, a location of the laser spot in the external scene and generates a symbol indicative of the location of the laser spot. The processor renders the symbol onto the external scene image to display an integrated image to a user.
