Experiments 1 & 2
For this experiment, exposure times were set for a total of 100ms with 18 uniformly spaced captures. In addition to the red, blue, and green filters used for the first experiment, we also used orange, blue-green, yellow and daylight filters (the first three of which were used for the second experiment). Singular values for the six filters used are:
[9.12 6.14
3.22 1.04 0.84
0.63].
This
indicates that the using 4 of the filters may be adequate for reasonable color
representation. This light source employed was somewhat ideal in that its power
in the infrared range was muted. Furthermore, these filters were especially
constructed for the light source, which simplified coupling of the two.
However, the power of the light source was much less than optimal,
necessitating long exposure times and close placement of the light source to
the dollhouse. This unfortunately introduced large amounts of shot noise, which
was visible in the resultant images. Dynamic range was extended by about 12 dB
at the high illumination end. Relevant plots and results are shown in the presentation. Click here for
