Transmitted Light Method
The transmitted-light-method (transillumination) can be very useful
with transparent objects like glass. The transillumination makes the
inner structures visible (Figure 44).
It is possible, for example, to depict the steel wire inside a security
glass or the liquid level within a bottle. X-ray images in medical
technology are also an example of transillumination.

3.6.3 Camera Setup
The FireWire-CAM offers a wide range of setting options that enable
it to be optimally adapted to the picture requirements.
The individual parameters are listed in section 3.4,
„Camera Settings“.
In the following paragraphs the settings used for typical automation
and visualization applications are described.
With visualization applications the focus of optimization is primarily
the picture as it is seen by the viewer (e.g. remote monitoring, security
applications). Automation usually requires constant environmental
conditions set according to the given task. The general visual
impression is therefore usually a secondary consideration. Instead it is
more important that the recognizable features for the subsequent
image processing are easily and reliably discernable.
Of course in practicle applications there may be instances where a
mixture of both requirement profiles is needed.
