Abstract

Regulating optical power levels within various systems, such as cameras, requires today an electronic feedback control or offline data processing, which introduces complex and expensive systems. Sometimes the blooming is such that data is lost and cannot be recovered by any sophisticated software. We explore the unique capabilities and advantages of nanotechnology in developing next generation non-linear components and devices to control and regulate optical power in a passive way. We report on the Dynamic Sunlight Filter (DSF) enabling High Dynamic Range (HDR) for various types of camera. The DSF solution is completely passive and can be added to any camera as an external add-on.
