The L3Vision™ digital L3C95EIA/CCIR 768x576
  • The L3C95 is fitted with e2v’s latest EMCCD sensor
  • Automatic control manages performance at all light levels
  • Analogue and digital USB2.0 outputs
  • DSP image enhancement gives outstanding low light performance

light levels
Light Levels
  • Light levels are described in terms of scene illumination
  • Bright daylight is in the region of 105 –106 lux
  • Quarter moon has a scene illumination of 10-2 lux
  • Starlight gives a scene illumination of 10-3 lux
  • L3C95 performance from daylight to below starlight is shown in the following video clip

technology comparison
Technology Comparison
  • The next clip compares the L3C95 with three low light technologies
      • The previous generation L3C65 EMCCD camera
      • The benchmark Gen3 intensifier (Omni IV) in an ICCD camera
      • The benchmark Sony EX view sensor widely used in CCTV
  • The L3C95 is significantly better than the previous generation
  • The L3C95 is better than the Gen3 Omni IV at all light levels
  • The L3C95 and the Sony CCD are equivalent in daylight but the Sony is unusable below quarter moon

l3c95 day night summary
L3C95 Day/Night summary
  • CCD quality video in daylight
  • AGC gives smooth transition as light level changes
  • Noise management enhances overcast starlight
  • Digital control gives scenario specific optimisation

conclusion
Conclusion
  • The technology is well characterised and understood
  • L3Vision™ gives CCD performance in daylight and ICCD performance at night without using an intensifier
  • It is a robust solid state solution for all light levels
  • It has the potential to extend operational capability
  • It is currently being deployed on operational mobile platforms
