Introduction
The four-bar target is used to calculate the resolvable temperature difference (minimum resolvable temperature difference, MRT) for MRT testing. Targets with different spatial frequencies correspond to targets with different test rates, and targets with different width dimensions and spatial frequencies can all match the rotating target wheel.
The triangle target is used to test the TOD (thermal image orientation discrimination) of infrared thermal imagers; the TOD parameter is similar to MRT D or MDT D testing. However, TOD or MDT D testing is more advanced in theory and practice.
The circular hole target is used to test MDTD (minimum detectable temperature difference parameter), and can also be used for axis alignment or aiming processes.
The square target is used to test parameters of NTD (Non-Destructive Testing) such as FPN (Fixed Pattern Noise), STF (Signal Transfer Function), and ATF (Aperiodic Transfer Function).
The slit target is made by processing rectangular patterns of different widths, and is used to test SRF (Slit Response Function)
The knife-edge target is based on testing the line spread function and MTF (Modulation Transfer Function) of the knife edge, and it is manufactured based on a sharply processed half-moon knife edge.
The cross-hole target is used for alignment, aiming and focusing functions, and it is manufactured based on machined holes and cross patterns.
The double four-bar target is based on its vertical and horizontal four-bar patterns, and is used for MRT D testing; it can also save testing time.
The multi four-bar target is a high-efficiency target for testing MRT D parameters. It has multiple four-bar patterns and can replace a series of single-pattern four-bar targets.
The multi-hole target is a high-efficiency target for testing MDTD (Minimum Detectable Temperature Difference) parameters, with multiple circular hole patterns; it can replace a series of single-pattern circular hole targets.
The cross target is used to evaluate the effectiveness of image processing in noise testing.
The contour target is used to evaluate the recognition range of the tested camera for real targets.
