SENSORS

 

The MRSG is equipped with a big variety of high-resolution customize and specialized hyperspectral (OCI-F hyperspectral Imager), multispectral (3P SLANTRANGE, Sequoia MicaSence), thermal (Flir Vue Pro R), and optical  (Sony A5100, Canon IXUS 160, Canon IXUS 140) sensors.

 

HYPERSPECTRAL CAMERAS:

  • OCI-F HYPERSPECTRAL IMAGER (VIS/NIR)

MRSG’s OCI™­F Series ("All-Seeing Eye") hyperspectral camera is optimized for VIS-NIR spectrum applications. Mounted on a UAV it is used for making accurate ground measurements, marine litter detection, and coastal mapping. This sensor is a miniaturized push-broom hyperspectral camera covering the full VIS-NIR (400-1000 nm) wavelength range, with a SuperSpeed USB 3.0 interface. It features ultra-compactness (14 cm x 7 cm x 7 cm) and lightweight (~ 570 g) with fast data transfer rates (up to 60 fps). As an innovative “true push-broom” hyperspectral imager, the OCI-F Series is not dependent on a constant scanning speed and it offers versatility on various platforms such as UAVs with perfect hyperspectral image stitching.

Key Specs:

  • “True push-broom” operation mode
  • 400-1000 nm spectral range
  • 240 spectral bands
  • 800 x scan length spatial pixels
  • 16 mm (21° FOV) lens

SPECTROMETER:

  • OCEAN OPTICS STS-VIS

A small spectrometer suitable for field spectral signature sampling. Connected with a Raspberry Pi micro-computer, powered by powerbank, this sensor can visualize its readings in real-time in the field through a wifi connection. MRSG possesses the version that takes measurments in the visible spectrum (350-800nm), making it an excellent instrument for marine applications.  

Key Specs:

  • 350-800 nm spectral range
  • Signal to noise ratio: >1500:1
  • Wavelength Accuracy: 0.13 nm
  • Size: 40x42x26 mm
  • Weight: 60g

THERMAL CAMERAS:

  • FLIR VUE PRO R

MRSG operates a FLIR VUE PRO RAD, 640, 13mm, 7.5Hz thermal camera. The Vue Pro R gives drone operators and certified thermographers the power to gather accurate, non-contact temperature measurements from an aerial perspective. Every still image the Vue Pro R saves contains accurate, calibrated temperature data embedded in every pixel, adding even more value to your sUAS operations and services than ever. Vue Pro R adds fully radiometric data-gathering to sUAS applications like building and roof inspections, power grid inspections, infrastructure analysis, precision agriculture, and public safety.

Key Specs:

  • Sensor Resolution: 640x512 Pixels
  • Lens Options: 13 mm
  • Field of View for NTSC Analog Output: 45°(H) x 37°(V) FoV
  • Frame Rate: 7.5Hz
  • Weight: 72 Grams
  • Dimensions (L x W x H): 2.26" x 1.75" (including lens)
  • Input Voltage: 4.0 - 6.0 VDC
  • Spectral Band: LWIR 7.5 µm – 13.5 µm

MULTISPECTRAL CAMERAS:

  • SLANTRANGE 3P

The two MRSG SLANTRANGE 3p multispectral cameras are uniquely customized having specific bands of Sentinel-2 and Sentinel-3 satellites, for mapping coastal environments. SLANTRANGE pioneered and patented a new approach to measurement accuracy with the introduction in 2014 of onboard, band-matched solar characterization, and radiometric calibration. The MRSG customized SLANTRANGE 3p consist of Innovative new design elements that run together through the integrated hardware/software architecture to deliver the most accurate measurements available for small aircraft:

  • Integrated solar spectrometer for frame-to-frame radiometrically accurate reflectance measurements (US Patents 9,470,579 and 9,791,316)
  • Individual lens characterization for precise dewarping and de-vignetting
  • Optimized algorithms for dynamic cross-channel registration
  • Smart Filtering™, which selectively samples scene elements to avoid the contaminating effects of background soils, shadows, specular reflections, or other noise sources.
