Problems solved by technology

The traditional method mainly uses the method of combining the turntable with the illuminator. Due to the large inertia of the turntable, this method can only achieve pointing to a single target in the field of view, and the cost is high.

The current multi-target tracking and indication technology mainly realizes the adjustment of the visual axis through the combination of optical system lenses. A multi-target tracking and indication technology based on optical phased array and inverse optics can properly combine the lenses of the optical system to achieve multi-target indication in a short time. And the beam pointing control speed is slow
