　・

The laser spot beam is irradiated about 18mm 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 40mm],

the center vibration width becomes be

- (2.5 + 2.5) = 40mm.

Standard after the gyro gain adjustment

1/5 = 8mm (Center vibration width)

Whole vibration width becomes be
8+ (2.5+2.5) = 13mm.

　・

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.
