High-Quality Lens less Imaging: Experiments and Theoretical Foundations

Abstract:
Lens less Imaging is a rapidly growing computational imaging modality in which measurements are encoded by non-traditional optics and computationally decoded to yield a reconstructed image. The
compact design, simple hardware, and large field-of-view offered by mask-based lens less imagers have shown promise in diverse applications including photography and microscopy. Lens less imagers can
compressively encode high-dimensional object properties in a single two-dimensional (2D) measurement. However, reconstructions often suffer from low resolution and quality.

We describe a computational camera that enables high-quality single-shot imaging with a random multi-focal lens let phase mask and simple software. We demonstrate high-resolution experimental reconstructions for photography and uncover fundamental system properties. We analyze the
performance of lens less imaging systems using a new theoretical framework based on information theory. Using this framework, we quantify tradeoffs and formalize the object-dependent nature of lens less imaging. We provide practical principles for the design of high-performance lens less imagers for future applications in photography and in vivo imaging.
