Abstract
A device for extracting at least one object characteristic of an object (106) is presented, the device comprising: a light sensor (101) for recording a hologram of an object and a processing unit (102) coupled to the light sensor and configured for extracting at least one object characteristic from the hologram; wherein the processing unit is configured for extracting the at least one object characteristic from a section of the hologram without reconstructing an image representation of the object. Further, a device (200) for sorting an object (106), a method for identifying an object and a method for sorting objects is presented.
Claims14
A device for extracting at least one characteristic of an object, comprising:
- a light sensor configured for recording at least a section of a hologram of an object, the light sensor consisting of a single row of light recording elements;
- and
- a processing unit coupled to the light sensor and configured for extracting at least one object characteristic from the hologram,
- wherein the processing unit is configured for extracting the at least one object characteristic from only a section of the hologram without reconstructing an image representation of the object.
A device for extracting at least one characteristic of an object, comprising:
- a light sensor configured for recording at least a section of a hologram of an object, the light sensor consisting of two rows of light recording elements intersecting each other thereby forming a cross-shape;
- and
- a processing unit coupled to the light sensor and configured for extracting at least one object characteristic from the hologram,
- wherein the processing unit is configured for extracting the at least one object characteristic from only a section of the hologram without reconstructing an image representation of the object.
A device for extracting at least one characteristic of an object, comprising:
- a light sensor configured for recording at least a section of a hologram of an object, the light sensor comprising optical in-coupling elements for recording the hologram;
- and
- a processing unit coupled to the light sensor and configured for extracting at least one object characteristic from the hologram,
- wherein the processing unit is configured for extracting the at least one object characteristic from only a section of the hologram without reconstructing an image representation of the object.
A method for extracting at least one characteristic of an object, the method comprising:
- providing a fluid sample comprising an object;
- illuminating the object;
- recording a hologram of the illuminated object;
- extracting at least one characteristic of the object from the recorded hologram;
- and
- sorting the object based on the extracted at least one characteristic of the object,
- wherein the extraction of the at least one characteristic of the object is performed using only a section of the recorded hologram, without reconstructing an image representation of the object.
