Metamaterials enable precise tailoring of light–matter interactions at the subwavelength
scale, permitting access to the full range of electromagnetic responses encoded in Maxwell's …

Modern digital cameras employ silicon focal plane array (FPA) image sensors featuring
millions of pixels. However, it is possible to make a camera that only needs one pixel. In …

信号采样是联系模拟信源和数字信息的桥梁. 人们对信息的巨量需求造成了信号采样,
传输和存储的巨大压力. 如何缓解这种压力又能有效提取承载在信号中的有用信息是信号与信息 …

摘要经典的香农采样定理认为, 为了不失真地恢复模拟信号, 采样频率应该不小于奈奎斯特频率(
即模拟信号频谱中的最高频率) 的两倍. 但是其中除了利用到信号是有限带宽的假设外 …

The production of pairs of entangled photons simply by focusing a laser beam onto a crystal
with a nonlinear optical response was used to test quantum mechanics and to open new …

The goal of this paper is to present a non-iterative and more importantly an extremely fast
algorithm to reconstruct images from compressively sensed (CS) random measurements. To …

Single-pixel imaging which employs active illumination to acquire spatial information is an
innovative imaging scheme and has received increasing attentions in recent years. It is …

Single-pixel imaging (SPI) has emerged as a powerful technique that uses coded wide-field
illumination with sampling by a single-point detector. Most SPI systems are limited by the …

Based on the classic augmented Lagrangian multiplier method, we propose, analyze and
test an algorithm for solving a class of equality-constrained non-smooth optimization …

Techniques from sparse signal representation are beginning to see significant impact in
computer vision, often on nontraditional applications where the goal is not just to obtain a …
