Infratest Camera Expert Pack is a premium module within the INFRATEST® software suite by HGH Infrared Systems. It is designed for demanding operators who need to qualify high-performance cameras and measure complex parameters. This pack includes advanced testing capabilities such as distortion mapping for fisheye optics, effective focal length calculation, and range estimation using the Triangle Orientation Discrimination (TOD) method.
Features
- Advanced Camera Properties:
- Field of View: Measured via square target extrapolation or high-accuracy rotation stage with pinhole/cross target.
- Distortion Mapping: Two methods—hole matrix comparison and scanning with rotation stages—support even fisheye optics.
- Effective Focal Length (EFL): Magnification of a square target through optics, excluding collimator contribution.
- Multiple Axes Alignment:
- Roll Difference Between Axes: Measures rotational offset between two video streams using square target imagery.
- Camera Performance Measurement:
- Automatic Gain Control (AGC) Latency: Time for AGC to adjust video signal after optical change.
- Spatial Latency: Time delay in video signal appearance from a triggered event.
- Focused Spatial Resolution:
- Modulation Transfer Function (MTF): Sine wave target method plots MTF curve using known values.
- Advanced Range Calculation:
- Minimum Detectable Temperature Difference (MDTD): Uses hole targets for thermal contrast analysis.
- Triangle Orientation Discrimination (TOD): Statistically robust method using triangle patterns to assess system performance. Based on TNO’s patented methodology.
Benefits
- High Precision Testing: Enables accurate measurement of complex camera parameters.
- Fisheye Optics Support: Distortion mapping methods accommodate wide-angle lenses.
- Advanced Range Estimation: TOD method provides more reliable and less subjective performance metrics.
- Real-Time Analysis: Immediate feedback on AGC latency, spatial resolution, and distortion.
- Modular Integration: Seamlessly connects with other Infratest modules and HGH hardware.
- STANAG Compliance: Aligns with NATO standards for electro-optical system testing.
- User-Friendly Interface: Simplifies advanced testing procedures for expert users.
