Deep Image Prior Amplitude SAR Image Anonymization

Synthetic Aperture Radar images are a powerful tool for studying the Earth’s surface. They are radar signals generated by an imaging system mounted on a platform such as an aircraft or satellite. As the platform moves, the system emits sequentially high-power electromagnetic waves through its antenna.

Spatial Calibration for Accurate Long Distance Measurement Using Infrared Cameras

All commercially available camera systems have lenses (and internal geometries) that cannot perfectly refract light waves and refocus them onto a two-dimensional (2D) image sensor. This means that all digital images contain elements of distortion and thus are not a true representation of the real world.

Towards Greater Sensitivity: A Brief FTIR and Infrared-Based Cavity Ring Down Spectroscopy Comparative Study

Cavity Ring-Down spectroscopy (CRDS) is a newer IR absorption-based technique made possible by the use of tunable pulsed lasers. Rather than using a broadband (blackbody) emitter as is done with traditional IR techniques, a pulsed laser is tuned across wavelengths into an optical cavity.
