| T104 |
0-100 |
Sentence |
denotes |
The scattering of light by small particles is described by Mie theory [27], and is quite non linear. |
| T105 |
101-301 |
Sentence |
denotes |
However, using the experimental setup described herein, these nonlinearities will smooth over to a large extent due to the breadth and angle of the laser cone, and wide distribution of particle sizes. |
| T106 |
302-398 |
Sentence |
denotes |
The brightness can, therefore, be taken as approximately proportional to the volume of material. |
| T107 |
399-575 |
Sentence |
denotes |
Although it is possible to extract pseudo-quantitative results from these images by merely summing up the brightness of each pixel, we caution against doing so for two reasons. |
| T108 |
576-736 |
Sentence |
denotes |
As seen in the no-mask image (Figure 3A), a narrow, fast-moving jet appears dim due to the small area of laser sheet it covers, despite carrying a large volume. |
| T109 |
737-801 |
Sentence |
denotes |
This weakness could be addressed by more complex image analysis. |
| T110 |
802-892 |
Sentence |
denotes |
Another caveat is that the results are dependent on the exact position of the laser sheet. |
| T111 |
893-1008 |
Sentence |
denotes |
In the configuration used in the current study, for example, any leakage from under the chin would not be detected. |
| T112 |
1009-1151 |
Sentence |
denotes |
However, when using additional laser sheets, it is apparent that almost all leakage occurs around the eyes and cheeks for the masks we tested. |
| T113 |
1152-1264 |
Sentence |
denotes |
These additional laser sheets complicate the interpretation of the images, even if using different laser colors. |
| T114 |
1265-1403 |
Sentence |
denotes |
Directing the cone straight onto the face to form a laser ring around the masks results in a large background scatter from the dummy skin. |
| T115 |
1404-1561 |
Sentence |
denotes |
Although this background can be reduced by black paint and image processing, this configuration would then require another laser sheet to detect penetration. |
