This paper expands on the research presented in 'An Advance in Infrared Lens Characterization: Measurement of the Lens MTF Using Common Undersampled IR Systems.' This update provides empirical data demonstrating the test system's performance through experimental modulation transfer function and encircled energy tests. This research also expands further on the software algorithms, describing the method used to obtain accurate real-time optical performance analysis. Real-time testing has a number of valuable applications, including focus optimization, prototyping, rapid/high-volume testing, and testing on-the-fly.
