Lensless Smart Sensor technology takes a novel approach to sensing by combining ultra-small diffractive gratings with standard image sensors. Light passing through the diffractive grating is intelligently spread onto the image sensor below to form an unrecognizable, but information-rich blob that contains all of the pertinent data from the scene. This information is combined with application-specific algorithms that can either visually reconstruct a scene, or extract relevant data, like the number and position of occupants directly from the blob. LSS uses the processed metadata to detect and interpret activity within a space at a size and performance previously unattainable with existing building sensing technologies, all without compromising privacy.
Through the use of diffractive optics, LSS captures information about a building’s occupants while fully preserving their privacy. The presence of someone, the number of people, and general activity can be passively detected, and used to trigger other systems and functions in the building.
LSS can also be deployed with thermal capabilities, so rooms can adjust automatically to the comfort level of occupants. Heating, cooling and lighting can be directed appropriately, and energy can be used only where needed. By rethinking the way digital systems see, LSS creates and intelligent infrastructure that can adapt to the ever-changing needs of a building’s occupants.
