・
The laser spot beam is irradiated about 5 mm in diameter at 5 m ahead.
①
To adjust the vibration width at the center of the
laser spot beam, measure the whole vibration width
first.
②
Subtract the radius of the laser spot (oblique lined
part) from the top and bottom of the measured
vibration width.
Example
)
△
When the whole vibration width is [About 45mm],
the center vibration width becomes be
45 - (2.5 + 2.5) = 40 mm.
Standard after the gyro gain adjustment
40
×
1/5 = 8 mm (Center vibration width)
Whole vibration width becomes be
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 0.02Step as shown below.
②
The peak section of the minimum vibration width can be obtained by the actual measured value.
③
Take the center of the peak section as the adjustment value.
