| 摘要 |
A retinal fundus imaging apparatus and method employing Maxwellian illumination is described. The retinal illumination is focused at and passes through an illumination region within a working area, the working area being within and concentric with the circular ocular lens. The working area also includes a second, collection region through which the retinal reflection passes. The two regions (that is, the illumination region and the collection region) are separated and located on opposing sides of the working area so as to reduce or substantially remove unwanted lenticular backscatter from the collection path. |
