Title: Innovations of Michael Lee Pappas
Introduction
Michael Lee Pappas is a notable inventor based in Anaheim, California. He has made significant contributions to the field of electro-optical sensors, holding two patents that showcase his innovative techniques. His work is primarily associated with Northrop Grumman Systems Corporation, where he has applied his expertise in developing advanced measurement techniques.
Latest Patents
Pappas's latest patents include a two-dimensional modulation transfer function measurement technique. This technique measures the Modulation Transfer Function (MTF) of an electro-optical sensor by focusing a square or rectangular target image onto the sensor. The MTF is derived in two directions simultaneously from the sensor's output. The target image is tilted concerning the sensor's focal plane array, allowing the edges to cross different detector elements at various phases. Additionally, the target image can be rotated over finely spaced intervals. The MTF can be calculated using a least squares method or a one-dimensional Fourier Transform in both horizontal and vertical directions.
Another significant patent is the Automated Minimum Resolvable Contrast (AMRC) test. This system automatically performs the Minimum Resolvable Contrast test on an image sensor, such as a TV camera. It utilizes a digital signal processor to control the testing process. An edge response from a square aperture target edge generates the MTF, which, combined with signal and noise data, provides input to the AMRC processing equations. This allows for the calculation of an AMRC output value. Alternatively, a slit target may be used instead of the square target aperture when measuring camera MTF.
