Measurement Area Configurations

The field of view or measurement volume is the area in which markers can be tracked. The PST Base HD can work with three different lense sizes: 3.5mm, 4.5mm and 8.5mm. The decision dependes on the specific requirements of the use case. The image below shows the field of view of the PST Base HD with each option.
