In particular, the present invention relates to a light directionality sensor that is capable of measuring light characteristics such as the light direction, light collimation, and light distribution. According to a first aspect of the present invention there is provided a light directionality sensor comprising a photo-sensor (2), comprising a plurality of photo-sensitive elements (3), and a plurality of light-absorbing light selecting structures (1) arranged on the photo-sensor so as to form an array of light-absorbing light selecting structures. In the array of light-absorbing light selecting structures, a succession of at least some of the light-absorbing light selecting structures has varying structural characteristics. The varying structural characteristics is achieved by each individual structure of the succession being formed such that it allows light within a different angle interval with respect to the array to be sensed. Further, according to a second aspect of the invention, there is provided a method for forming a light sensor according to the first aspect of the present invention."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light directionality sensor","description":"The present invention relates to light sensors for measuring light characteristics.
