Abstract: An ophthalmic imaging system includes a first lens group, an illumination light source, an imaging module, a fixation light, a reflective element, at least one light-blocking member, and a first polarizer. The first lens group includes an aspheric first lens. The fixation light provides a light beam and includes at least three light-emitting components. The reflective element is configured to reflect the light beam and direct the light beam towards the aspheric first lens. The light-blocking member is disposed downstream from and in a light path of the fixation light and disposed upstream from and in a light path of the reflective element. The first polarizer is disposed downstream from and in the light path of the fixation light and disposed upstream from and in the light path of the reflective element to polarize the light beam.

Abstract: A projection device is disposable into a display platform of a display rack having a plurality of display platforms, for directly projecting an image frame onto a projection screen of the display platform. The image frame projected to the projection screen is not reflected by any reflective mirror arranged between the projection device and the projection screen. A length of the image frame in a first direction is equal to at least ten times a length of the image frame in a second direction. Since no reflective mirror is arranged between the projection device and the projection screen, the projection device is more easily applicable to display racks.
