ARL at UH develops sensors and technologies that support research on land, in air and in water with the ultimate goal of characterizing the environment from the atmosphere into the deep ocean. Data acquired by precise and timely remote sensing and in situ instrumentation supplies models with information for validation and enhancement to support Naval requirements. UH has extensive experience in development of remote sensing electro-optical instrumentation for DoD and civilian applications. This includes development and long-term use of atmospheric Light Detection and Ranging (LiDAR), space-sensor calibration, Raman spectrometers, passive and active hyperspectral sensors, infrared sensors, sensors that measure in-water optical properties, and optical communications. ARL at UH identifies sensors developed in support of specific scientific goals that have dual-use applicability and works in close collaboration with innovative technologists to maximize the science return from technology and ensure the scientific fidelity of the technology development. Sensors in these collaborations have been incorporated into a variety of platforms including small satellites (in partnership with the Hawaii Space Flight Laboratory), manned airplanes and helicopters, research vessels, unmanned aerial, surface and underwater systems, and underwater cabled and land-based observatories.
