Results Overview
Scale Error
Scale error was determined by measuring the dimensions of several
small holographic models overlaid in TCH and subsequently
comparing these dimensions against the true model proportions. The
overall expected scale error is calculated by assessing the observed
dimension divided by the true dimension, In this testing / d . s = d
obs true
environment, the model in TCH was on average 99.97% the size of
the control model, thereby making the average scale error -0.03%.
Drift Error
Assessing drift error was split into two components:
1)Coordinate-based comparison and 2)Baseline based
comparison. Coordinate-based comparison offers an
indication of the model's accuracy in positioning
holograms in the real world. However, this is highly
dependent on the user's ability to precisely anchor and
orient the model time after time. Inspecting baseline
lengths is independent of this human error, as the
observed model positions are used to calculate distances
which can be compared against expected values.
Overall, WLT significantly diminished the impact of drift. Comparing the observed model
coordinates to their expected locations highlighted a decrease in error of 3x, going from
1.14% to 0.37% over distance between the two solutions. When comparing the two solutions
via baseline length, it was found that drift was reduced by 4x, shrinking from 1.27% to 0.31%
