Bokode Experiments Data

Number of Light Sources

Varying Number of Light Sources
Data was collected in a dark room with a flourescent lamp with
4 lamp settings. The image on the left is of the Bokode with no
ambient illumination. The images below are of the Bokode under 4 different
illumination settings. No exposure adjustment in the images taken.

Distance between Light Source and Bokode

Changing distance to light source
Data collected in dark room with same fourescent lamp light source.
Two bulbs are illuminated and the light source is gradually moved closer to the Bokode.
No exposure adjustment in the images taken.

Viewing Angle

angle_1 Changing Bokode viewing angle. Image on left is at 0 deg rotation.
Images below are of the Bokode rotated from this optimum viewing
angle. The exposure has been adjusted in each image for
optimum viewing.

are of the Bokode at its maximum readable
range (2 meters with 15 micron 10x10 Data Matrix code).
Below are the images taken to determine the
maximum range. The exposure has been adjusted
in each image for optimum viewing.

High Resolution Range Experiments

Images taken of One Dimensional Bokode from an interval of ranges.
Range is from 5cm to 140cm in 5 cm increments. The Bokode is positioned
at 0 degrees heading from the camera lens, and no exposure adjustments
are made between images.
