Automated lens adjustment for hyperspectral imaging

A method comprising:

• storing, in one or more data storage devices, focus adjustment data for an imaging system that includes a tunable lens, wherein the imaging system comprises an electrically-controllable element configured to selectively set each of multiple different spectral bands for image capture, and wherein the focus adjustment data indicates different focus adjustment parameters corresponding to the different spectral bands;
• selecting a spectral band from among the multiple different spectral bands;
• controlling the electrically-controllable element to set the selected spectral band for image capture;
• retrieving the focus adjustment parameter that corresponds to the selected spectral band;
• controlling the tunable lens to adjust the tunable lens based on the retrieved focus adjustment parameter that corresponds to the selected spectral band;
• and
• capturing an image of a subject using the image sensor while the electrically-controllable element sets the selected spectral band for image capture and while the tunable lens is adjusted based on the retrieved focus adjustment parameter that corresponds to the selected spectral band.

One or more non-transitory computer-readable media storing software instructions that, when executed by one or more processing devices, cause the one or more processing devices to perform operations comprising:

• storing focus adjustment data for an imaging system that includes a tunable lens, wherein the imaging system comprises an electrically-controllable element configured to selectively set each of multiple different spectral bands for image capture, and wherein the focus adjustment data indicates different focus adjustment parameters corresponding to the different spectral bands;

• retrieving the focus adjustment parameter that corresponds to the selected spectral band;
