ON Semiconductor : Optische Sensoren in Smart Mobile Devices
Abstract Smart mobile handheld platforms continue to integrate an ever increasing spectrum of functions from multiple communication standards to a wide array of user interface features and sophisticated power management. This paper explores advances in optical sensors as they apply to enhancing the user experience and extending battery life. Developments in ultra-low power optical proximity sensors are enabling distance measurement and contactless gesture detection while simultaneously supporting novel power management techniques. Integration with traditional ambient light sensors optimizes display power while maintaining satisfactory illumination.
