Performance of the Southern Astrophysical Research Telescope Speckle Instrument [PDF]

arXiv
The High Resolution Camera (HRCam) speckle imager at the 4.1 m Southern Astrophysical Research telescope is a highly productive instrument that has accumulated about 40K observations to date. Its performance (detected flux, level of the speckle signal, signal-to-noise ratio, and limiting magnitude) is studied here using both the actual data and ...

Hyperspectral image reconstruction by deep learning with super-Rayleigh speckles [PDF]

arXiv
Ghost imaging via sparsity constraints (GISC) spectral camera modulates the three-dimensional (3D) hyperspectral image into a two-dimensional (2D) compressive image with speckles in a single shot. It obtains a 3D hyperspectral image (HSI) by reconstruction algorithms.

A ghost imaging framework based on laser mode speckle pattern for underwater environments

Communications Engineering
Due to the complex physical processes found in underwater environments, such as absorption, scattering, and noise, it is challenging to obtain high-quality images using conventional camera-based imaging techniques.
