Table 18: First and second delay rule for SkyWriting |
|---|
Parameters |
Suggested values |
Effect if value is too low |
Effect if value is too high |
|---|---|---|---|
StartLength |
= Scanner Lag |
Laser shots are too narrow at the start of a vector. |
No problem, just increasing mark time. |
EndLength |
= Scanner Lag |
Laser shots are too narrow at the last part of a vector |
The last part of a vector is marked too long. |
Jump Delay |
normal |
Oscillations could occur at the start of a vector. |
No problem, just increasing mark time. |
Mark Delay |
= 0µs |
No problem. |
No problem, just increasing mark time. |
Poly Delay |
normal |
The corners of the polyline are rounded off. |
Burn-in effects at the corners. |
LaserOn Delay |
= StartLength + Scanner Lag |
The first part of a vector is marked too soon. |
The first part of a vector is not marked. |
LaserOff Delay |
= 1µs |
First delay rule for SkyWriting must be true. |
The last part of a vector is marked too long. |
