The present invention encompasses methods and apparatus for focusing and autofocusing light imaging systems so as to improve image clarity and resolution. The method utilizes programming logic responsive to the transmission, absorption, or reflectance of light (40) from a target (20) onto a detector (32). The programming logic compares real-time detection data with previously stored data to determine the degree of focus of the light source on the target. The programming logic then adjusts the focal length of the light source (10) and the target (20) based on the degree of focus of the light source on the target. Preferably, the invention is used in conjunction with a laser imaging system. |
