Linearity and artefacts are recognizable with HDO

Visible proof of linearity

Red line in the top window should be linear = linear deflation

• linearity is a key prerequisite for accuracy
• loss of linearity: curve instead of linear line

Visible detection of artefacts

Artefacts are strong signals which are misleading and need to be detected

• Artefacts are clearly detectable on screen
• Visible control how the technology takes care of them
