Figure 5–40. Real Red Laser Image Pattern
Figure 5–40 shows a real red laser image pattern for the 5.2 meter gas cell,
with the input window on the left, and the output window on the right.
12. Once the desired image pattern shown in
the exit image is clearly positioned on the output window, it is time to
adjust the relay mirrors, 4, 5 and 6 shown in
these mirrors to maximize the IR signal (Max) on the interferometer
display as shown in
