DMSC-MK2 UV-Visible-NearIR Sensor

About
Our staff has operated various aerial sensors since 1994 and has strong expertise in domestic and international mission planning, data collection and post processing.

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.
  • FOV: 29.3° XY and 41.5° Diagonal.
  • Integrated operation with DGPS for positional accuracy.
  • System allows in-flight optimization of the radiometric intensity range thus optimizing the instrument's radiometric range and signal-to-noise ratio.
  • Very high S/N capabilities, along with narrow field-of-view Nikon lenses producing imagery with considerably less vignetting effects than other systems.
  • Comprised of three compact components for extraordinary portability and troublefree mounting on small aircraft.
