Interference Stripe Noise Reduction of CMOS Sensor-Based Digital Holographic Measurement System

Abstract: Comparing with the application of charge coupled device (CCD) sensor, a kind of interference stripe noise (ISN) can be observed easily from the complementary metal-oxide-semiconductor (CMOS) sensor-based digital holographic measurement (DHM) system because a series of optic coatings and filters are used in front of that sensor in order to improve its imaging effect. The improper assembly or the micro manufacturing error of these optic components may create the unexpected interference phenomena in the imaging s… Show more

“…Second, after laser processing, the ablation diameters of femtosecond laser are measured by typical SEM images. The image features of Gray-Level Co-occurrence Matrix (GLCM) [13] are also computed for SEM images. Third, a Support Vector Regression (SVR) [14] is trained by the laser process parameters and GLCM image features above for the laser ablation diameter prediction.…”
