I'll just say it was a very hard problem in imaging. A solution involving the confluence of hardware, optics, software and real-time FPGA-based very high resolution image processing. We even had to go as far as to develop manufacturing techniques that involved assembling electronics in a vacuum chamber. Given the application I can't say any more than that.
