Abstract

The invention relates to an optical sensor device ( 100 ) that comprises a plurality of objectives ( 152 ) for generating primary images of corresponding sensor regions ( 111 ). The primary images are then mapped with intermediate optics ( 153 ) onto a detector plane ( 154 ), particularly onto the sensitive plane of an image sensor.

First claim

The invention claimed is:

1. An optical sensor device, comprising:
a) a plurality of sensor regions;
b) a plurality of objectives that are arranged such that each objective generates a primary image of one of the sensor regions,
wherein at least one of the objectives has a numerical aperture larger than 0.1 and comprises several lenses;
c) a light detector with an array of detector pixels;
d) intermediate optics that maps primary images of the objectives onto the detector plane, wherein at least one primary image is mapped onto the whole detector plane; and
e) a light source for generating an input light beam (L) that is directed towards the sensor regions.

2. An optical sensor device, comprising:
a) a plurality of sensor regions;
b) a plurality of objectives that are arranged such that each objective generates a primary image of one of the sensor regions; and
c) a light detector with an array of detector pixels as detector plane onto which said primary images are mapped, wherein at least one primary image is mapped onto the whole detector plane.

3. The optical sensor device according to claim 1 ,
wherein at least one of the objectives has a numerical aperture larger than 0.1, preferably larger than 0.25.

4. The optical sensor device according to claim 1 ,
wherein at least one of the objectives comprises several lenses.

5. The optical sensor device according to claim 1 ,
wherein the intermediate optics comprises a multiplexing unit for selectively mapping different sets of primary images onto the detector plane.

6. The optical sensor device according to claim 1 ,
wherein the intermediate optics comprises reflecting, refracting, and/or diffracting elements.

7. The optical sensor device according to claim 1 ,
wherein the light source configured to generate the input light beam (L) that is totally internally reflected and/or scattered at the sensor regions.

8. The optical sensor device according to claim 7 ,
wherein the light source is adapted to selectively illuminate separate sensor regions.

9. The optical sensor device according to claim 1 ,
wherein the detector plane comprises an array of detector pixels.

10. The optical sensor device according to claim 1 ,
further comprising an image processing unit configured to process images generated on the detector plane.
