연속적으로 회전하는 폴리곤 미러 휠을 기반으로 하는 RIEGL VQ-1460 스캔 메커니즘은 직선으로 평행한 스캔 라인을 제공하여 지면에 규칙적인 점 패턴을 만듭니다.
트랙을 따라 동일한 공간 샘플링 주파수로 객체 범위가 잘 정의되어 작은 객체도 감지할 수 있습니다.
RIEGL VQ-1460의 폭넓은 스캔 범위 (FOV)와 다중 시간 측정 기법 (Multiple-time-around measurement)은 이 시스템을 광대역 매핑 응용 분야에 보다 완벽하게 지원합니다.
또한 높은 레이저 펄스 반복 속도로 높은 고도에서 스캔 작업을 가능하게 하여 불필요한 비행 시간을 최소화함으로써 데이터 수집에 있어 최고의 효율성을 갖도록
설계되었습니다.

- rounded average PRR
- Typical values for average conditions and average ambient brightness; in bright sunlight the operational range may be considerably shorter and the operational flight altitude may be considerably lower than under an overcast sky.
- The maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility of 40 km. Range ambiguities have to be resolved by multiple-time-around processing.
- If the laser beam hits, in part, more than one target, the laser’s pulse power is split accordingly. Thus, the achievable range is reduced.
- Typical values for max. effective FOV 60°, additional roll angle up to ± 5°
- Above Ground Level
- Nominal Ocular Hazard Distance, based upon MPE according to IEC 60825-1:2014, for single line condition
- Extended Nominal Ocular Hazard Distance, based upon MPE according to IEC 60825-1:2014, for single line condition
- NOHD and ENOHD have been calculated for a typical angular step width of 0.013° (which means non-overlapping laser footprints), and an aircraft speed higher than 10 kn. NOHD and ENOHD increase when using overlapping laser footprints which may be intended e.g. for power line mapping.
- The atmospheric attenuation of the laser beam is taken into account assuming standard clear conditions with a visibility of 23.5 km. Absorption by water vapor and carbon dioxide is neglected.
