Vehicles are designed with a broader array of capabilities to sense their occupants. They can monitor the driver’s alertness and let occupants interact with the console using touch sensing or with gesture recognition. In the event of a collision, sensors can help provide critical information about the position and attention of occupants to activate restraints and deploy airbags in the best possible manner. II-VI’s products enable the most advanced in-cabin control and monitoring systems for the latest applications in human-vehicle interactions. Our vertical cavity surface emitting lasers (VCSELs) are ideal for optical touch sensors situated on the dashboard or steering wheel. Our VCSEL arrays can provide infrared cabin illumination and structured light projection to enable gesture recognition. Our micro-optics can isolate the returning VCSEL signal over a wide field of view to improve the sensors’ sensitivity and accuracy, whether in intense sunlight or at night time. Active coatings such as indium tin oxide (ITO) can also be deposited on our micro-optics in complex patterns and used to monitor light leakage from a physically damaged sensor.
