ABSTRACT
The emergence of commercial time of flight (ToF) cameras for realtime depth images has motivated extensive study of exploitation of ToF information. In principle, a ToF camera is an active sensor that emits an amplitude modulated near-infrared (NIR) signal, which illuminates a given scene. The per-pixel phase difference of the modulation between reflected light and a reference signal determines the path length, and hence a depth map, of the scene.

Multifrequency minimum shift keying
A new modulation scheme that produces a constant envelope continuous phase signal set with a compact power spectrum and power efficiency better than that of MSK is proposed. The scheme can be implemented by quadrature-carrier multiplexing of two ...
Doppler time-of-flight imaging
Over the last few years, depth cameras have become increasingly popular for a range of applications, including human-computer interaction and gaming, augmented reality, machine vision, and medical imaging. Many of the commercially-available devices use ...
Fourier Analysis on Transient Imaging with a Multifrequency Time-of-Flight Camera
CVPR '14: Proceedings of the 2014 IEEE Conference on Computer Vision and Pattern RecognitionA transient image is the optical impulse response of a scene which visualizes light propagation during an ultra-short time interval. In this paper we discover that the data captured by a multifrequency time-of-flight (ToF) camera is the Fourier ...
