Sensors Unlimited introduces new InGaAs SWIR cameras with advanced dynamic range enhancements

Sensors Unlimited - Goodrich ISR Systems of Princeton, NJ, USA has introduced two cameras with advanced imaging enhancements that expand the dynamic range of short wave infrared (SWIR) imagery, says the firm.

Due to technological advances, the new indium gallium arsenide (InGaAs) SWIR SU320KTX (320 x 240 pixel format with 40 micron pixel pitch) and the SU640KTSX (640 x 512 pixel format with 25 micron pixel pitch) cameras are able to automatically compensate for variations in light levels that may differ by up to five orders of magnitude. This increase in dynamic range addresses the demand for improved imaging and surveillance in military, medical, and commercial applications.

The firm adds that the cameras are easy to integrate into mobile, handheld, or aerial surveillance systems, and feature low power consumption. The simultaneous RS170 analog and 12-bit CameraLink digital outputs provide easy plug-and-play video and high quality images for image processing or transmission.

Furthermore, SWIR technology is able to detect reflected light at wavelengths that the human eye cannot see, providing real-time daylight-to-low-light imaging. This makes these imagers ideal for surveillance, laser detection, emission microscopy, imaging spectroscopy, astronomy, and imaging through fog, dust and smoke.

The new cameras provide the highest sensitivity available in the SWIR 0.9 to 1.7 micron spectrum, claims the firm. The optional NIR/SWIR models extend the range of operation down to 0.7 and up to 1.7 microns. Building on the firm’s solid-state, room-temperature FPA technology, the improved InGaAs-SWIR cameras employ a new on-board automatic gain control (AGC) and adjustable enhancement thresholds. The built-in non-uniformity corrections (NUCs) address the challenges of urban night imaging without blooming.
