Advanced hot image analysis

On pages 21-22 we talked about hot images and hot image
analysis. In short, after splicing the FSU 995 FA automatically
calculates a splice loss estimation and makes available two
hot images. To see analysis of these hot images, press HOT
IMAGE when one of the cold images is on the screen. The
hot image that comes up will indicate which of the two im-
ages it is---here, “Ist Image.”

Light intensity curves
Hot image with graphs
3-D light intensity curves
The final level of advanced hot image analysis are three-
dimensional light intensity curves. The scale is 20
m
m be-
tween ticks along the longitudinal axis of the fiber and 15
m
m
between ticks along the transversal axis of the fiber.
Press ESC when you want to exit from advanced hot image
analysis.
The next level of analysis includes three sets of graphs:
A
On the far left are two graphs showing the hot fiber index
level from the upper view and the lower view.
B
In the center are found two graphs that show the core
deformations (dotted line) and the base line tilting (solid line)
at a magnification of 15x, measured both longitudinally (top)
and transversally (bottom).
C
On the far right are two graphs that measure the core
diameter as seen from the top and bottom.
Press VIEW to access the final level of analysis.
This will bring up the first of the three levels of advanced hot
images. The first includes light intensity curves, which can
be used to determine the type of fiber being spliced. We
have seen them earlier in the section on fiber types on pages
26-7. The “1ST IMAGE” indicates that it is the first of the two
hot images taken during the splicing sequence.
