The DMSC-MK2 UV-Visible-NearIR Sensor, made by SpecTerra Ltd. in Australia, provides 12-bit imagery from 4 customizable wavelength channels at 25cm - 2m resolution. The system is very portable and suited for research and operational mapping work worldwide in a broad variety of aircraft. Our team is also skilled in ground-truthing and ancillary data collection.

Some specifics and advantages of this sensor are:

Portability:
Main unit measures approximately 9x9x12 inches and is controlled via a laptop interface. 24-28V DC or 115-220V AC power source can be derived either directly from the aircraft or from batteries (draw is <10Amps).

12-Bit Radiometric Resolution:
Allows very broad brightness range for diverse substrate conditions with extremely high signal-to-noise ratio.

Customizable Channel Wavelengths:
Interference filters are used to select each of the 4 channels’ spectral range. This allows customization of the channel combinations to maximize detection or separation capabilities for specific substrates.

Customizable Spatial Resolution:
The DMSC can be flown at any altitude above approximately 1800’, resulting in spatial data resolutions of 25cm to 2+m. Successful data acquisitions are possible under clouds, thus lessening the dependence on clear weather.

Features and Specifications

• Four progressive-scan CCD cameras.
• Spectral range capability from 350nm to 990nm.
• 1024 x 1024 pixel format.
• Captures 12-bit digital data.
• Utilizes four narrow bandwidth (10-20nm) interference filters which may be interchanged to customize the sensor to particular applications.
• Capable of .25 to 5 meter spatial resolution.
• 24 mm focal length f/2.8 35mm format lenses ensuring excellent image geometry.
