Linear diode array

The scintillation screen converts the photon energy emitted by the x-ray tube into visible light on the diodes.

The diodes produce a voltage when the light energy is received.

This means that it is capable of generating useful data when x-raying both very thick (tread) and thin (sidewall) sections of a tire simultaneously.

However, the human eye is capable of visualizing only a small fraction of the LDA's full dynamic range.

To compensate for the limitations of the human eye while still taking advantage of this feature of the LDA, a variety of selectable contrast and brightness enhancing tables are available.
