Figure 2. Tripod
There is an option whether to incorporate the tripod 3-axis adjustable head in the setup. The tripod head allows for
additional degrees of freedom and more adjustability. However, the more degrees of freedom that are present in the
system, the less rigid the system is. For a more rigid system, it is suggested to forgo the use of the tripod head, unless the
additional adjustability is critical. Note that there is adjustability provided by the tripod, slide block and hinge as well. For
use of the tripod head, proceed to Step 2. To forgo use of tripod head, please skip to Step 4, Part b.
