Transient imaging with a time-of-flight camera and its applications

Jing-yu Lin, Ri-hui Wu, Hong-man Wang, Ye-bin Liu,jylin@gxu.edu.cn,liuyebin@tsinghua.edu.cn

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 9,   Pages 1268-1276 doi: 10.1631/FITEE.1700556

Abstract: is a technique in photography that records the process of light propagation before it reaches a stationary state such that events at the light speed level can be observed. In this review we introduce three main models for with a : correlation model, frequency-domain model, and compressive sensing model. applications usually involve resolving the problem of light transport and separating the light rays arriving along different paths. We discuss two of the applications: imaging objects inside and recovering both the shape and texture of an object around a corner.

Multi-aperture optical imaging systems and their mathematical light field acquisition models Review Article

Qiming QI, Ruigang FU, Zhengzheng SHAO, Ping WANG, Hongqi FAN

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 823-844 doi: 10.1631/FITEE.2100058

Abstract:

Inspired by the compound eyes of insects, many s have been proposed to improve the imaging quality, e.g., to yield a high-resolution image or an image with a large field-of-view. Previous research has reviewed existing s, but few papers emphasize the which is essential to bridge the gap between configuration design and application. In this paper, we review typical s (i.e., , , and ), and then summarize general mathematical s for different configurations. These mathematical models provide methods for calculating the key indexes of a specific , such as the field-of-view and sub-image overlap ratio. The mathematical tools simplify the quantitative design and evaluation of imaging systems for researchers.
