Computational-Pixel Imager (CPI) Cameras

CPI Technology Features:

  • Long-wave, mid-wave, or dual-band infrared imaging
  • In-pixel spatial and temporal processing
  • On-chip electronic image stabilization
  • Simultaneous multi-mode operation
  • User programmable operational modes
  • Supports event imaging

Advantages Compared to Others:

  • Highest dynamic range
  • Lowest noise equivalent delta temperature (NEdT)
  • Fastest frame rate
  • Fastest scanning, either continuous or step-stare motion
  • Programmable on-chip data processing
CPI technology offers new advances to infrared imaging system developers.  It removes many of the constraints currently imposed on developers by the limitations of the imager.   The digital-pixel readout integrated circuit (DROIC) within a CPI enables both performance and functionality benefits.  Unlike conventional infrared imagers, digital-pixel devices do not saturate when viewing bright scenes.  They can also readout data at a high rate without incurring a noise penalty.  The CPI DROIC can process information on-chip, prior to read out, avoiding the bottleneck that is present in all other infrared imagers.  On-chip processing enables the user to access more information from the scene – either spatial, temporal, or spectral.  Much of the cost and complexity of an advanced sensor system can be reduced by implementing CPI technology.  CPI cameras are available in several varieties, either with closed-cycle cryo-coolers or liquid nitrogen pour-fill dewars.   Standard or custom camera cores are also available for purchase.

Example Camera Use Cases:

  • Laboratory experiments for R&D
