Because of the breadth of applications for optical sensors, the challenges to the design and functioning of an optical sensor for a particular purpose requires intimate knowledge of optical, material and environmental properties that affect sensor performance across physical scales. Sensors addresses all aspects of optical sensors from source and detection technologies, sensor configurations and processing approaches to applications. The meeting is arranged in broad topic categories and themes accessible to researchers at any career stage. Beyond the topic categories, the meeting explores the use of Artificial Intelligence and Machine Learning (AI/ML). Contributed talks in this area of research are welcomed.
