However I will say, it's possible we may not need to increase resolution. Rather, we may possibly instead use a steerable optic component like a mirror to direct incoming light to the sensor from the direction you're likely to be in. First it does an initial sweep over a wide range to find possible tracking targets, and then when it has found one, it keeps tracking you. I'm sure that has its own set of challenges to solve, but it could be worth it over increasing the raw resolution of the sensor.
