The invention relates to the technical field of reflection imaging systems, in particular to a compact eyeball tracking imaging device, which comprises an illumination device, an imaging device and a control device, and is characterized in that the illumination device projects illumination light to the eyes of a user at a first preset angle, so that the eyes generate eye reflection light at a second preset angle; the light receiving part of the prism lens module is vertically arranged relative to the eye part; the light receiving part receives the eye reflected light, and the prism lens module converts the eye reflected light into horizontal emergent light and projects the horizontal emergent light to the imaging surface of the photosensitive chip, so that the photosensitive chip obtains a reflected image of the eye. Eye reflected light of a user can be projected into the prism lens module which is arranged below the eyes in the horizontal direction by projecting a light source at a specific angle, and then a
