Methods, systems, and apparatuses for a hyperspectral plenoptic camera. A hyperspectral plenoptic camera may be configured with a filter in the aperture plane of the camera. The filter may selectively transmit radiated wavelengths to a microlens array, which may focus and transmit the wavelengths to an image sensor based on, e.g., the location and intensity of the wavelengths. One or more lenses and/or an iris may be configured to collect, focus, and/or transmit wavelengths to and from the filter. The filter may be located between two lenses, and the distance between the two lenses may be based on a diameter of an aperture of the plenoptic camera.

Hyperspectral plenoptic camera

Methods and systems are disclosed for deriving quantitative measurements of an imaged material using plenoptic imaging. In one or more embodiments, image data is generated by a plenoptic camera having a filter configured to transmit a plurality of different spectra in different regions of the filter. A set of plenoptic image data is produced by determining respective sets of pixels in the image data corresponding to the different regions of the filter and determining light intensities of the plurality of different spectra for respective super-pixel groups of the pixels in the image data. One or more additional quantitative measurements of an imaged material are then derived from a comparison of the determined light intensities of two or more of the plurality of different spectra.
