Thermal imaging is an essential tool in a wide variety of research areas. In this work we demonstrate high-throughput double-wavelength temperature distribution imaging using a modified single-pixel camera without the requirement of a beam splitter (

This paper discusses the noisy phase retrieval problem: recovering a complex image signal with independent noise from quadratic measurements. Inspired by the dark fringes shown in the measured images of the array detector, a novel phase retrieval app

We present a new technique to denoise a single-pixel camera, in which complementary compressive imaging and a threshold strategy have been combined to improve image quality. The number of measurements recorded by the detector is reduced by setting a

In this paper, a two-position rotating grating compressed sensing spectrometer is proposed, which can expand the spectrum measurement range nearly twice without losing high resolution. In the entire measurement process, two compressed sensing samples

An experiment on compressive microscopic imaging with single-pixel detector and single-arm has been performed on the basis of “positive–negative” (differential) light modulation of a digital micromirror device (DMD). A magnified image of micron

A new type of compressive spectroscopy technique employing a complementary sampling strategy is reported. In a single sequence of spectral compressive sampling, positive and negative measurements are performed, in which sensing matrices with a comple

An experimental demonstration of spectral imaging with measurement dimensions compressed has been performed. With the method of dual compressed sensing (CS) we derive, the spectral image of a colored object can be obtained with only a single point de

We report an experimental demonstration of spectral imaging with a spectrometer without any scanning. The spatial resolution is provided by spatial light modulation based on the theory of compressed sensing. Objects with both continuous and discrete

Single-pixel imaging technology has significant imaging advantages in the invisible wavelength and low light environment. Considering the energy compressive characteristic of discrete cosine spectrum, a single-pixel microscopic compressive imaging me

In the context of correspondence ghost imaging, we utilize the correlation coefficients to separate the reference detector speckle patterns into positive and negative correlated parts. A positive image and a negative image of the object are obtained
