摘要
Combination of optical encoding and algorithmic decoding provides high-performance and high-functional imaging modalities known as computational imaging. Multi-aperture optics has been effectively utilized as an optical encoder and enables us to implement novel imaging methods and systems. In this paper, two instances of computational imaging using multi-aperture optics are presented with different types of apertures embedding in the optical system. A compound-eye imager is a flexible and versatile imaging system composed of multiple image fields, which was applied to intra-oral diagnostics. Single-shot phase imaging capable of capturing a large complex field is achieved by multi-aperture optics with a coded aperture. In both cases, the encoded signals are processed to retrieve desired information under the framework of computational imaging.
