    ... there are mainly two methodes - most used is "trianglation", where a camera detects the exact position of a laser spot "off-axis" to the camera, so there's a displacement relative to the distance.

    The other methode is "Time Of Flight" - here a super-short laser pulse is emitted and the time until the reflection is detected in a sensor near to the emitter is direct proportional to the distance of the reflective spot on a surface ...
