High-contrast grating

WebThe improvements due to small incision lenticule extraction (SMILE) in vision, e.g., in spherical equivalent (SE) and visual acuity (VA), has been widely recognized. However, the contrast sensitivity (CS) change after SMILE was not certain. Here, we investigated the effect of SMILE on CS before, 1 day after and 7 days after surgery and then clarified the … Webcreation of coupled cavity systems.7 However, HCGs make use of high-index-contrast to achieve high re ectance; they are often surrounded by air and require relatively complex fabrication processes to remove the sacri cial layer under the HCG layer.1 Suspended, they are susceptible to vibrational instability,8 ine cient in heat dissipation, and ...
