Coherent Diffractive Imaging and Its Application in Energy Materials and Devices Study

Lenses are dominantly popular in various imaging systems, either as objective optics to form images directly or as focusing optics for scanning microscopy. While a lens-based imaging system is elegant and intuitive, the lens also limits achievable image quality. Alternative approaches seek complementary imaging methods without physical image-forming lenses, thus eliminating the associated limitations. Coherent diffractive imaging (CDI) emerged as one of the lensless imaging techniques, which can provide a diffraction-limited resolution with multiple contrasts.
