Apparatuses and methods involving multi-modal imaging of a sample

An example apparatus includes a light source, first and second polarizers, an image sensor, a filter, and control circuitry. The light source outputs a light beam, and the first polarizer passes first polarized light from the output light beam and toward a sample. The image sensor collects light reflected from the sample responsive to the passed first polarized light. The second polarizer passes second polarized light from the reflected light and toward the image sensor. The filter selectively passes the reflected light in a visible light range and near infrared range (NIR) light range toward the image sensor. The control circuitry causes the first and second polarizers to adjust to different polarization angles, and collects the image data of the sample from the reflected light.
