Abstract
Implementations of the present disclosure provide devices including a camera that is operable to provide images, a deposition head, the deposition head being configured to selectively deposit the RMA to the area of skin, and being positioned to at least partially obscure the area of skin relative to a viewing field of the camera, and a prism attached to the deposition head, the prism being configured to direct light reflected from the area of skin to first camera to enable the camera to generate images of the area of skin. Accordingly, the deposition head is able to physically occupy a column directly over the area of skin, while the camera is able to view the area of skin through the prism. In some examples, prism surfaces can be curved to provide a telecentric view of the area of skin.
