"correction requires slow, repeated calculations/ measurements, or bulky extra hardware, overcome using titanium dioxide nanopillars on glass assigning unique visual signature to each optical distortion type...  deep neural network instantly reads signature from single snapshot, diagnosing error/ directing correction... functions across multiple light wavelengths/ complex beam shapes, lightweight/ compact... astronomy, precision manufacturing, deep-tissue endoscopy, military, autonomous vehicles"
