Compressive imaging in scattering media

Interferometry-based modal analysis with finite aperture effects

“…through the use of regularizers and studying its implications on data acquisition (e.g., recovering signals from a reduced number of measurements [13]), very little is known about the interplay of hardware limitations and signal reconstruction. Moreover, Among such limitations are the limited number of degrees of freedom of actual acquisition systems [14], [15], the finite aperture size of the optical components [16], and their finite spatial resolution (e.g., Spatial Light Modulators (SLMs), and Digital Micromirror Devices (DMDs)) [13], [8], [17], [18], to name a few. To underscore the importance of both studying and addressing such limitations, in the sequel we provide examples from the literature concerning their consequential impact on signal reconstruction.…”

Full-color stereoscopic imaging with a single-pixel photodetector

“…Moreover, single-pixel detectors provide a broader spectral range compared to conventional cameras, permitting to extend imaging techniques to different spectral regions [14,15]. Furthermore, it has been proved the ability of single-pixel cameras to perform non-invasive imaging through scattering media in biological tissues [16,17]. All these advantages could make single-pixel imaging a relevant technique in biomedical imaging, where fast, highresolution, multispectral, and tolerant to scattering imaging is required.…”

Optimal compressive multiphoton imaging at depth using single-pixel detection

“…The total diffuse signal is recorded by a single-pixel detector, and a minimisation algorithm is used to recover the image. This alleviates the need for spatial coherence in the detection path [15], enables compressive sensing [11], and can also be performed in parallel, supporting fast acquisition times [12].…”
