Abstract
An optoelectronic sensor is provided that has an image sensor for the detection of image data in its field of view and an aiming device having a light source that is arranged laterally offset from the image sensor and that is configured to generate alignment light and thus a light pattern in the field of view to make the position and/or extent of the field of view in space visible. In this respect, the aiming device has at least one optical metaelement having a metasurface and/or a metamaterial that is arranged and configured such that the optical axes of the image sensor and the aiming device are coaxially superposed.
Claims19
An optoelectronic sensor, the optoelectronic sensor comprising:
- an image sensor for the detection of image data in a field of view and an aiming device having a light source, the light source being arranged laterally offset from the image sensor and the light source being configured to generate alignment light and thus a light pattern in the field of view to make the position and/or extent of the field of view in space visible,
- wherein the aiming device has at least one optical metaelement having at least one of a metasurface and a metamaterial that is arranged and configured such that the optical axes of the image sensor and of the aiming device are coaxially superposed.
A method of visualizing a field of view of an optoelectronic sensor that detects image data from the field of view by an image sensor and that irradiates alignment light by means of an aiming device by a light source arranged laterally offset from the image sensor and thus generates a light pattern in the field of view to make the position and/or extent of the field of view in space visible,
- wherein the aiming device has at least one optical metaelement having a metasurface and/or a metamaterial that coaxially superposes the optical axes of the image sensor and the aiming device.
