ABSTRACT
The limited pattern area of periodic nanostructures limits the development of practical devices. This study introduces an X-ray interference lithography (XIL) stitching technique to fabricate a large-area (1.5â
cm × 1.5â
cm) two-dimensional photonic crystal (PhC) on the YAG Ce scintillator, which functions as an encoder in a high numerical aperture optical encoding imaging system to effectively capture high-frequency information. An X-ray imaging experiment revealed a substantial 7.64â
dB improvement in the signal-to-noise ratio (SNR) across a large field of view (2.6â
mm × 2.6 mm) and achieved comparable or superior image quality with half the exposure dose. These findings have significant implications for advancing practical applications of X-ray imaging.
