摘要：
Methods and systems for acquiring and/or projecting images from and/or to a target area are provided. Such a method or system can includes an optical fiber assembly which may be driven to scan the target area in a scan pattern. The optical fiber assembly may provide multiple effective light sources (e.g., via a plurality of optical fibers) that are axially staggered with respect to an optical system located between the optical fiber and the target area. The optical system may be operable to focus and/or redirect the light from the multiple light sources onto separate focal planes. A composite image may be generated based on light reflected from and/or projected onto the separate focal planes. The composite image may have an extended depth of focus or field spanning over a distance between the separate focal planes while maintaining or improving image resolution.
