Compressive sensing (CS) has been intensively studied as a super-resolution technique in image acquisition and reconstruction. It has also been introduced into three-dimensional (3-D) laser imaging to enhance the spatial resolution of images obtained from the existing few-pixel array sensors. These approaches, however, either suffer from low-range resolution or lack long-range detecting abilities....Show More
Hyperspectral (HS) imaging has achieved breakthroughs in many applications, such as remote sensing and object recognition. However, the spatial resolution of HS images is still insufficient due to the limitations of sensor technology and cost. In this article, we propose an HS image superresolution method that combines low-resolution (LR) HS images and high-resolution (HR) panchromatic (PAN) image...Show More
The resolution of nonscanning three-dimensional (3-D) imaging systems is limited by the number and accuracy of the array sensors. Moreover, for space-continuous targets in practical situations, the echo pulses in time-of-flight systems overlap and traditional peak detection is no longer suitable for super-resolution applications. Hence, compressive sensing (CS) has been introduced to achieve super...Show More
Nitride phosphors are widely used in manufacturing white light emitting diodes (LEDs). A visible light communication novelty using nitride phosphor is proposed to realize spectrum shift in light signal reception. Using the phosphor to experiment, the results demonstrate that the optical energy conversion efficiency achieves 80%, the optical transmission reaches 95%. The signal eye diagram represen...Show More
