Hyperspectral plenoptic camera

1. A plenoptic camera, comprising:

a filter located between a first lens and a second lens in an aperture plane of the plenoptic camera, wherein the filter is configured to selectively permit transmission of wavelengths;

a micro lens array, wherein each micro lens of the micro lens array is configured to, based on a location of the wavelengths, focus the wavelengths from the filter; 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

an image sensor, configured to receive the focused wavelengths.

2. The plenoptic camera of claim 1 , wherein one of the two lenses is configured to be adjusted with respect to the image sensor.

3. The plenoptic camera of claim 1 , wherein the filter is configured to selectively transmit a continuous range of wavelengths.

4. The plenoptic camera of claim 1 , further comprising: an iris, configured to focus the wavelengths relative to the image sensor.

5. The plenoptic camera of claim 1 , wherein the filter is located in the aperture plane of the plenoptic camera such that a center of the filter is imaged by a center of a first micro lens of the micro lens array.

6. 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.

7. The method of claim 6 , wherein one of the two lenses is configured to be adjusted with respect to the image sensor.

8. The method of claim 6 , wherein the filter is configured to selectively transmit a continuous range of wavelengths.

9. The method of claim 6 , further comprising:

focusing, using an iris of the plenoptic camera and based on a location of the image sensor, the wavelengths.

10. The method of claim 6 , wherein the filter is located in the aperture plane of the plenoptic camera such that a center of the filter is imaged by a center of a first micro lens of the micro lens array.

11. 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.

12. The system of claim 11 , wherein one of the two lenses is configured to be adjusted with respect to the image sensor.

13. The system of claim 11 , wherein the filter is configured to selectively transmit a continuous range of wavelengths.

14. The system of claim 11 , further comprising:

an iris, configured to focus the wavelengths relative to the image sensor.
