Recent advances in lensless imaging

Abstract

Lensless imaging provides opportunities to design imaging systems free from the constraints imposed by traditional camera architectures. Thanks to advances in imaging hardware, fabrication techniques, and new algorithms, researchers have recently developed lensless imaging systems that are extremely compact, lightweight or able to image higher-dimensional quantities. Here we review these recent advances and describe the design principles and their effects that one should consider when developing and using lensless imaging systems.
