In the video, the Continental rep says "120 degree field of view" and "reaching out as far as thirty meters".[1] This may be the short range model for bumper height applications.
ASC has built units with much longer ranges.
For more range, you need bigger collecting optics, which means a bigger unit, or a narrower field of view. The tradeoffs are straightforward.
You also have to spread the laser output over a wider area to keep it eye-safe. The laser eye-safety requirement is on power through a 1/4" hole, corresponding to the pupil size of an eye. This protects people staring directly into the emitter. The power can be greater if the beam is wider. If you devoted the top inch of the windshield to sensors, and spread the laser output over a wide area of windshield, the power could be much higher.
