Abstract
Provided is a compact spectrometer including a light blocking layer having an aperture, a micro lens provided in contact with the light blocking layer, the micro lens being configured to collimate light having passed through the aperture, a filter array configured to filter the collimated light, and a photodetector array configured to detect the filtered light.
Claims20
A compact spectrometer comprising:
- a light blocking layer having an aperture;
- a micro lens which directly contacts the light blocking layer, the micro lens being configured to collimate light having passed through the aperture;
- a filter array configured to filter the collimated light;
- and
- a photodetector array configured to detect the filtered light.

A compact spectrometer comprising:
- a light blocking layer having an aperture;
- a micro lens which contacts the light blocking layer, the micro lens being configured to collimate light having passed through the aperture;
- a filter array configured to filter the collimated light;
- and
- a photodetector array configured to detect the filtered light,
- wherein a focal plane of the micro lens is aligned with a surface of the micro lens that is in contact with the light blocking layer.
3 more elements
A bio-signal measuring apparatus comprising:
- a compact spectrometer array;
- and
- a processor configured to obtain a spectrum for each position of an object based on light detected by the compact spectrometer array, and to estimate bio-information of the object by analyzing the obtained spectrum for each position of the object or to obtain depth information of the object by analyzing the obtained spectrum for each position of the object,
- wherein each compact spectrometer comprises:
- a light blocking layer having an aperture;
- a micro lens provided in contact with the light blocking layer, the micro lens being configured to collimate light having passed through the aperture;
- a filter array configured to filter the collimated light;
- and
- a photodetector array configured to detect the filtered light.
