Latest Patents

Yuhui Cheng holds a patent titled "Modulation transfer function test compensation for test pattern duty." This invention focuses on improving the accuracy of frequency response measurements of linear systems using modulation transfer function test compensation. The optical imaging system illuminates and images an input test pattern, while a processor measures a modulation transfer function. The processor also determines a compensating factor for error in the input test pattern duty cycle. The driving function for the measurement is a test pattern with a periodic waveform approximating a square wave, which may have an error in duty cycle. A windowed fast Fourier transform on a grayscale image of the test pattern generates odd harmonics. Adjusting the amplitude values of these odd harmonics corrects for the error in the resolution target duty cycle. Yuhui Cheng has 1 patent to her name.
