Target patterns for electro-optical system performances measurement
HGH’s wide range of target patterns are optimized for specific tests for visible to infrared instruments :
Harmonization (pinhole or cross-hair) target – Optical axis alignment
Align the optical axes of multi-channel optronic systems with precision. The harmonization target ensures all optical paths are perfectly aligned for peak system accuracy.
Square target – Field of view (FOV) measurement
Used to determine the FOV, this target helps validate that your camera accurately captures the desired scene within the correct spatial limits.
Distortion target – Image distortion analysis
Identify and correct lens distortions such as barrel and pincushion effects. This target supports precise geometric calibration.
Knife-edge target – MTF evaluation
Measure the modulation transfer function (MTF) to evaluate spatial resolution. The high-contrast edge allows detailed analysis of image sharpness.
Slit target – LSF measurement
Analyze line spread function (LSF) to assess the system’s response to fine lines and spatial detail, critical for system resolution validation.
4-bar target – Thermal resolution (MRTD)
Evaluate the minimum resolvable temperature difference of infrared cameras. This is key for calculating the range of thermal imagers.
Triangle target – Triangle Orientation Discrimination (TOD)
Measure the performances and the range of any Thermal Imager using the most advanced, bias-free procedure.
Target patterns dimension accuracy
| Dimension > 1000 µm: | ±30µm |
| 250µm < Dimension< 1000µm : | ±3%+3µm |
| 100µm < Dimension < 250µm : | ±10µm |
| Dimension < 100µm: | ±5µm |
All targets are supplied with a certificate of compliance with measurement uncertainty ± 2 µm
Targets dedicated for visible to SWIR cameras and Night Vision Devices
USAF1951 visible target – Standardized spatial resolution testing
The most universally used standardized pattern for testing spatial resolution, the USAF1951 target includes varying bar sizes to evaluate and benchmark the resolution of optical systems. Also available with various contrasts for MRC (Minimum Resolvable Contrast) measurement.
Multi-contrast target
This target with linear and logarithmic successively contrasted areas is used for dynamic range of visible to SWIR cameras measurement.
