Targets for infrared and visible test

HGH can provide a wide range of targets of various patterns and sizes for characterization of visible and infrared optronic systems. 

Targets adapted to your tests

HGH's targets can be mounted onto a collimator target wheel or directly onto the front of a blackbody or visible source. A high accuracy sensor enables real time measurement of target temperature.      

Target patterns and dimensions depend on the type of test being carried out and on the camera characteristics. 

The most frequently used patterns are: 

Pin-hole target
Harmonization target (pinhole) for optical axis alignment of the UUT optronic system
Square target
Square target for field of view measurement
Distortion target
Distortion target for distortion image measurement
Half-moon target
Half-moon target for Modulation Transfer Function calculation (MTF)
Slit target
Slit target for Line Spread Function calculation (LSF)
4-bar target
4-bar target for thermal resolution measurement of infrared camera (MRTD: Minimum Resolvable Temperature Difference)

HGH can design/supply any type of patterns for emissive or reflective targets. Tell us about the level of performance you want to measure and we will design the appropriate target.
