厂商公布的测程条件(原文):
a) Under line-of-sight conditions, with visibility not less than 26 km and humidity not greater than 50% (at 30 °C), the ranging distance for a vehicle target (3 m × 3 m) is ≥ 18,000 m. b) Under line-of-sight conditions, with visibility not less than 30 km and humidity not greater than 50% (at 30 °C), the ranging distance for a target with diffuse reflectance not less than 30% (6 m × 6 m) is ≥ 23,000 m.

量程数字只在该条件成立。能见度、靶标尺寸、靶标反射率任一变化,量程都会大幅偏离;
我们不把数字外推到厂商没测过的靶标。
怎么用这个型号
- 它是器件,不是整机:给你激光通道、接收与数据接口,光学、结构、安全分类由你的产品负责。
- 正式分类是你的责任:模组文档写的是模组的等级,装进整机后要重新评估可达发射量。
- 先看量程条件,再看量程:把上面的原文条件和你自己的靶标对一遍,再决定要不要测。
