Hyperspectral Non-Imaging Sensors

SSSC non-imaging sensors are ideal for recording the behavior of energetic point targets.  Like a relatively wide field-of-view spectrometer, these “pseudo-imaging” systems are employed on operational platforms and in the lab to exploit the unique spectral-temperature signatures of fast, energetic events.

• Crossed Dispersion Prism (CDP) spectral-temporal sensor technology (US patents 7,155,354 and 7,499,836)
• Relatively wide field-of-view spectrometer concept (not a “soda straw”)
  
• Based on an innovative optical element called the Crossed Dispersion Prism
• Pseudo-imaging process
• Detection of uncued dynamic events (staring)
• Sub-pixel location accuracy

• Very broad spectral ranges (VIS through MWIR)
  
• Moderate spectral resolution (~280 colors)
  
• Single frame spectral characterization
  
• Very fast data acquisition and processing
  
• Suitable for airborne platforms
  
• No moving parts
