Abstract
Introduced here are retinal cameras having optical stops whose size can be adjusted to enable self-alignment by naturally guiding an eye toward a specified location. Generally, a retinal camera will constrict the bounds of an optical stop until the optical stop is aligned with the eye. In some embodiments, the optical stop is mechanically resized as a subject shifts their eye. In some embodiments, the optical stop is digitally created using a pixelated liquid crystal display (LCD) layer having multiple pixels that are individually controllably. In some embodiments, multiple non-pixelated LCD layers are connected to one another to form a variable transmission stack. In such embodiments, the size of the optical stop can be varied by changing which LCD layer(s) are active at a given point in time.
