The laser spot beam travels 5-m ahead, irradiating with spot of approx. 5 mm in diameter.
①
The vibration width is adjusted at the center of
the laser spot. First, measure the whole vibration
width.
②
Subtract the top and bottom radial parts (shaded
areas) of the laser spots from the measured whole
vibration width.
e.g.
)
When the vibration width as a whole is "approx.
45 mm",
Vibration width of center is:
45 - (2.5 + 2.5) = 40 mm.
Standard figure after the gyro-gain adjustment

×
1/5 = 8 mm (Vibration width of center)
Vibration width as a whole is:
8+ (2.5+2.5) = 13 mm.
・
How to obtain the minimum value of the vibration width
①
Measure the vibration width while changing the adjustment value that is set every 0.02-Step as shown
below.
②
The peak zone of the minimum vibration width can be obtained by the actual measured value.
③
The center of the peak zone becomes the adjustment value.
