Abstract

Super-resolving readout systems using an apodizer are effective for achieving high-density optical recording.¹,²,³ These systems need additional optics that include a narrow slit and focusing lens for suppressing enlarged sidelobes. However, the added optics reduce the readout signal power and require precise positioning of the slit. In this study, we demonstrate a super- resolving readout system that employs an electrical equalizer instead of additional optics.
