Hyperspectral plenoptic camera

A method comprising:

• receiving, via an aperture of a plenoptic camera, wavelengths;
• filtering, using a filter located between a first lens and a second lens located in an aperture plane of the plenoptic camera, the wavelengths, wherein the filtering comprises selectively permitting transmission of the wavelengths;
• focusing, via a micro lens array and based on a location of the wavelengths, the wavelengths onto a sensor, wherein a distance between the micro lens array and the second lens is based on a diameter of an aperture of the plenoptic camera;
• and
• outputting, by the plenoptic camera and using an image sensor, an indication of the location and intensity of the wavelengths.

A system comprising:

• a filter located between a first lens and a second lens in an aperture plane of a plenoptic camera, and
• a sensor region of the plenoptic camera;
• wherein the filter is configured to:
• receive, via an aperture, wavelengths;
• and
• filter the wavelengths by selectively transmitting a first set of the wavelengths to the sensor region;
• and
• wherein the sensor region is configured to:
• receive the first set of the wavelengths;
• and
• focus, using a micro lens array and based on a location of the wavelengths, the wavelengths onto an image sensor, wherein a distance between the micro lens array and the second lens is based on a diameter of an aperture of the plenoptic camera.
