Infratest Camera Expert Upgrade is an enhancement module for the Infratest Camera Pack, developed by HGH Infrared Systems. It equips users with advanced testing capabilities for high-performance cameras, enabling precise measurement of complex parameters such as distortion, effective focal length, gain control latency, and range estimation using the Triangle Orientation Discrimination (TOD) method. This upgrade is ideal for demanding operators in R&D, production, and quality assurance environments.

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

• Enhanced Testing Capabilities: Adds expert-level tools to the standard camera pack for deeper analysis.
