What is RPP ?
Random Pattern Projector (RPP) is a divergent dot matrix pattern of NxM pixels with a ratio of bright and dark pixels
of approximately 10%. Each bright pixel is surrounded by at least 8 dark pixels with no contact between bright pixels.
The bright pixels distribution is pseudo-random and the pattern is symmetric with respect to the center. Multiple laser
projectors can be tiled to obtain a larger area while maintaining the same random pattern.

Focusing Options
The focusing of the light pattern is very important parameter as it is directly proportional to the resolution one can attain for structured lighting applications. It is important
to note the relationship between focus and depth of focus (i.e. Range where the thickness remains within 1.4 times minimum), the tighter the focus that can be attained
the smaller the depth of focus. At Osela we provide many different focusing options giving you the flexibility to choose the one that best suits your application.

Note on depth of focus: using the definition of depth of focus: range of positions where the spot size is smaller than √2 times the smallest beam size at working
distance and removing the range behind the laser, there is a point where the function become linear and all focus options have the same slope.
Limit of validity of figure 2 Option D: 2500mm Option B: 750mm. Behind this points the dept h of field is ~1.33*working distance for all options.
