Patent ID: 8115813

Claim:
An optical system for capturing images of a printed circuit board having a set of first portions and a set of second portions, comprising: a first set of cameras arranged in a first linear array, each of the first set of cameras configured to receive first light originating from each of the set of first portions of the printed circuit board, the first light transmitting along a first optical path defined between each of the set of first portions and each of the first set of cameras correspondingly; a second set of cameras arranged in a second linear array, each of the second set of cameras configured to receive second light originating from each of the set of second portions of the printed circuit board, the second light transmitting along a second optical path defined between each of the set of second portions and each of the second set of cameras correspondingly; and an optical assembly disposed along at least one of the first optical path and the second optical path, the optical assembly operable to direct the first light and the second light toward the first set of cameras and the second set of cameras between the printed circuit board respectively; wherein the optical assembly comprises a set of first reflectors and a set of second reflectors, each of the set of first reflectors reflects the first light to each of the first set of cameras, and each of the set of second reflectors reflects the second light to each of the second set of cameras, the set of first reflectors and the set of second reflectors are selected from the group consisting of reflecting mirrors and total reflective prisms.
