**Target albedo = 0.1 small craft, 0.85 large craft @ 1,570nm.
Laser Safety
***AS/NZS IEC60825.1 2011.
Transmitter
| Laser type |
diode pumped Nd:YAG/OPO |
| Wavelength |
1,570 nm |
| Output |
nominally 8mJ [to Class 1M limit] |
| Ranging rate |
up to 30Hz [with duty cycle] |
Detector
- InGaAs with time variant gain
Range Determination
- Signals from the detector are digitally sampled and examined to determine all potential real target returns. An adaptive range threshold compensates for changing noise levels, maximising system capability under varying conditions.
