Image Sensors and Cameras Based on Colloidal Quantum Dots for Defense Applications
This article reports on the image sensor technology and the VS20 camera product developed at Emberion. The article describes the image sensor design comprising the sensor stack based on a p-i-n photodiode implementation with PbS QDs sandwiched between thin-film hole transport (HTL) and electron transport (ETL) layers as well as the CMOS ROIC architecture and pixel front-end interfacing the photodiode stack.

How Laser Communications Innovation is Finally Coming of Age and Driving Innovation in Defense
Though laser technology has advantages over radio, and those advantages are growing as innovation accelerates, what is essential to realize is that they need not be in competition.

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.

Determining Optical Material Parameters With Motion in Structured Illumination
Ellipsometry measures the amplitude ratio and the phase difference between polarized light reflected from the surface of a film and determines the refractive index or thickness by fitting the experimental data to an optical model that represents an approximated sample structure.

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.
