SenSim – EO and IR sensor simulation with real time effects. An advanced sensor modelling toolkit and library for the real-time simulation of sensor effects, from any optical sensor in the Electro-optic (EO) or Infrared (IR) passbands.

SenSim provides engineering level modelling of the optics, detector, electronics and display components, of optical sensors, simulating appropriate modulation transfer functions (MTFs), detector sampling, noise, non-uniformity, dead-detectors, fill-factor, 1/f and white noise, pre-and post-amplifiers, and displays. SenSim can use the actual sensor component specifications to provide the most realistic sensor visualisation experience.

SenSim consists of two component technologies: SenSimMT, the sensor design modelling tool, and SenSimRT, the real-time sensor effects Library.


  • A powerful tool for sensor design and analysis studies. Users enter typical or known sensor specifications, and dynamically view the effect as it would appear on an actual sensor display.
  • Models all sensor components: optics, detector configuration, signal processing and display system.
  • Assimilates either a static sensor image or synthesizes a tactical scene on-the-fly with a target model at range, based on user-specified inputs. Using advanced engineering models for simulating the sensor effects, SenSimMT produces a play-back movie of that sensor against the user-specified scenario, for checking and analysis.
  • With the precise specifications for the sensor look-and-feel, SenSimMT outputs the run-time data constructs to be used by SenSimRT for real-time sensor effects implementation.


  • A GPU-based real-time sensor effects library that integrates easily into existing image generators. SenSimRT applies the appropriate blurring, noise, and even physically-corrects NVG light-point haloing, in the frame-buffer of nVidia and ATI advanced graphics boards.
  • Using a SenSimMT output file, SenSimRT configures itself to apply engineering-level NVG and FLIR sensor effects at the specified sensor frame rate (upto 60 Hz at 800x600), depending on the SenSimMT design and graphics hardware.
  • Efficient GPU algorithms apply the effects to the at-aperture imagery in the frame-buffer with very minimal impact on scene rendering performance. The result is real-time advanced sensor effects on low cost PC-based hardware. SenSimRT will also run on tightly-coupled dual GPU hardware architectures, like SLI from nVidia, for larger at-aperture image-processing at 60 Hz or better frame-rates.
