NIR/SWIR Cameras for Unmanned Vehicles

Sensors Unlimited, Inc. (Princeton, NJ) offers the KT series of NIR/SWIR cameras for UAV and UGV (unmanned aerial and ground vehicle) applications. The cameras feature the night vision and laser detection capability that images from the near infrared (NIR) to the shortwave infrared (SWIR) portion of the spectrum, including what night vision goggles can and cannot see. Available in lightweight, high sensitivity camera packages with 320 × 256 pixel or 640 × 512 pixel resolution.

Ruggedized Lenses

Resolve Optics Ltd (Chesham, UK) has produced ruggedized lenses to meet specified environmental tests such as Def Stan 00-35, which includes vibration, shock, and bump testing over a temperature range of -40° to +70° C. Lens optical coatings can be applied to meet a range of MIL Spec standards (including MIL-C-14806, MIL-C-675, MIL-M-13508) to ensure the coatings do not craze, peel, or succumb to fungal attack. To minimize the risk of condensation, the lenses are assembled in a dry nitrogen atmosphere.

Near IR Joulemeters and Radiometers

The deltΔ NIR Joulemeter from Spectrum Detector (Lake Oswego, OR) provides near-IR spectral response from 0.9 to 1.7 um. The deltΔ probe plugs into an analog power module (APM) to mate with oscilloscopes and lock-in amplifiers, or plugs into a digital USB-based electronic module (DPM) to create a complete PC based energy meter. LabView software controls range, wavelength, trigger level, graphic displays. The deΔ NIR Joulemeter features germanium or In- GaAs detectors.

16 Channel Framing Camera

Specialised Imaging Ltd (Hertfordshire, UK) has introduced a 16 channel camera capable of capturing images at 200,000,000 frames per second with gating down to 5ns. Applications for ultra high speed multiple framing cameras include material studies, automotive, aerospace, high voltage electrical discharge research, plasma display studies, and microdevices. The SIM-16 framing camera offers the choice of 4, 6, 8 or 16 separate optical channels without compromising performance or image quality. An integral TFT monitor allows users to see what the camera sees in real-time.

Chip-On-Board Illuminance Sensor

Hamamatsu Corporation (Bridgewater, NJ) has introduced a chip-on-board-type illuminance sensor called the S10604. The RoHS-compliant sensor is ideal as an energy-saving sensor for large-screen TV brightness control, as a backlight dimmer in liquid-crystal displays on cell phones, and in other applications where the level of the ambient light is measured. The S10604, which has a package size of 2.0mm × 1.25mm × 0.8mm, is the same size as typical chip resistors.
