| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Lasers (lasers) | required | 82% | expert_inference | Lasers is modeled as a necessary component or method for this technology in the current graph. |
|
| Digital Signal Processing (DSP) (digital_signal_processing) | enabling | 68% | expert_inference | Digital Signal Processing (DSP) provides a capability that enables this technology without being the only possible path. |
|
| Semiconductor Devices (semiconductor_devices) | enabling | 68% | expert_inference | Semiconductors enable detector and control components for many laser scanners, but the class is broader than one mandatory component. |
