Hybrid sensor system and method for providing 3D imaging

A method of providing an image based on a hybrid sensing array, the method comprising:

• detecting, by a 2D sensing region of the hybrid sensing array, first light;
• detecting, by a 3D depth sensing region of the hybrid sensing array, second light different from the first light;
• directing, by a first nanostructure of a metalens on the hybrid sensing array, the first light reflected from an object towards the 2D sensing region;
• directing, by a second nanostructure of the metalens of the hybrid sensing array, the second light reflected from the object towards the 3D depth sensing region;
• and
• combining 2D image information provided by the 2D sensing region and 3D depth information provided by the 3D depth sensing region to generate a combined image.

A 3D sensing system comprising:

• a 2D sensing region to detect first light;
• a 3D depth sensing region to detect second light;
• a metalens covering the 2D sensing region, the metalens comprising a first nanostructure and a second nanostructure, the first nanostructure being configured to direct the first light reflected from an object towards the 2D sensing region, and the second nanostructure being configured to direct the second light reflected from the object towards the 3D depth sensing region;
• and
• a processing circuit configured to:
• determine 2D image information of the object based on the 2D sensing region;
• determine 3D depth information of the object based on the 3D depth sensing region;
• and
• update the 2D image information of the object with the 3D depth information.
