    Combining a line laser, SWIR camera, and drone technology provides PV plant operators with a contactless solution to improve their ongoing inspection processes.
    FIGURE 1. Free-space optical (FSO) communication basic principle.
    A shortwave-infrared camera is specially designed for use in closed-loop adaptive optics for free-space optical communications.
    The C-BLUE One scientific CMOS camera features a 1608 × 1104 monochrome CMOS sensor with a 660 fps frame rate.
    Quantum efficiency (QE) as a function of wavelength for the C-RED 3 camera is shown at three different operating temperatures. The slight shift of response toward longer wavelengths and slight decrease in QE as temperature decreases should be inconsequential for normal use in AO for a FSO system. In addition, for portable FSO use at differing temperatures, the camera has an adaptive bias-plus-dark correction that is automatically updated based on any temperature changes.
    A shortwave-infrared (SWIR) camera for adaptive optical (AO) systems used in free-space optical communications is lightweight while maintaining low noise and high frame rate.

    FIGURE 1. Utah’s Salt Lake Valley occasionally experiences an atmospheric phenomenon that traps air pollution for days or weeks at a time. During these atmospheric inversion events, ground-level visibility is severely reduced. These images taken from a video show visible imagery (a) and shortwave-infrared (SWIR) imagery (b) during a period of very low ground-level visibility on December 7, 2017 at approximately 3:30 pm MST (to see the video, visit https://youtu.be/3cBkfQb8vxQ). The SWIR imagery was captured at 60 fps with the Sensors Unlimited GA1280JSX mini-SWIR area camera and a 200 mm SWIR-optimized f/1.6 lens. The visible imagery was captured with a Nikon D5100 DSLR camera in video mode and a 55–200 mm f/4.5-5.6 lens. Both sets of imagery are cropped, but are otherwise unchanged.
    Covert operations commonly use thermal imaging and/or night vision, but the shortwave infrared (SWIR) band has its own advantages, such as seeing through atmospheric haze.

    Test fringes obtained with the MIRC-X instrument and C-RED One are displayed. Top is the image without gain, equivalent to the one obtained with a classical scientific infrared camera; bottom is the image obtained with C-RED one, showing the spectacular increase of signal to noise ratio when avalanche gain is applied.
    Low-noise infrared cameras are opening new perspectives in infrared interferometry for astronomy.
    FIGURE 1. The C-RED One camera (a) with sub-electron-noise 1750 frames/s e-APD imager can be operated in extreme and remote locations with only an electrical power supply and water cooling; its outer skin and input window have been removed to show internal components. A close-up (b) shows the cold finger before integration of the cooled focal plane array inside the camera package.
    Electron-initiated avalanche photodiodes using mercury cadmium telluride semiconductor materials have improved SWIR imaging.
