Abstract
Examples of the present disclosure relate to a system in a vehicle for reducing oncoming light. The system includes a windshield. The system includes a sensor installed in the vehicle to detect a light from an oncoming light source. The system includes a wave cancellation unit to generate destructive interference light based on the detected oncoming light source and project the destructive interference light into the windshield.
Claims18
A system in a vehicle for reducing oncoming light, comprising:
- a windshield;
- a sensor installed in the vehicle to detect light from an oncoming light source;
- and
- a wave cancellation unit to generate destructive interference light based on the detected light from the oncoming light source and project the destructive interference light into the windshield, wherein the generated destructive interference light comprises a waveform with a phase offset to the detected light from the oncoming light source.

A method for reducing apparent oncoming light in a vehicle, comprising:
- detecting, via a sensor, oncoming light;
- and
- generating, via a wave cancellation unit, destructive interference light based on the detected oncoming light, wherein the generated destructive interference light comprises a waveform with a phase offset to the detected oncoming light.
A wave cancellation apparatus, comprising:
- a processor;
- a sensor communicatively connected to the processor;
- and
- a light generation device communicatively coupled to the processor, wherein the processor is to cause the light generation device to generate a destructive interference light in response to detecting an oncoming light in sensor data from the sensor, wherein the generated destructive interference light comprises a waveform with a phase offset to the detected oncoming light.
