An apparatus is disclosed for alignment of a line sensor camera by laser. The apparatus provides line-by-line photographic frames of a material below, these lines being along an axis transverse to a linear axis in the direction of movement. The apparatus includes a line sensor camera. The line sensor camera includes a front cover having a pair of pinholes, wherein a first pinhole is for absolute linear and transverse alignment and a second pin hole is oblong for final transverse adjustment leeway. The front cover also has a pair of screw holes. The camera also includes a lens affixed to the front cover and adjusted to see a focal line on the material, a line sensor to convert light to electric charge, a mechanical housing to align the lens to the line sensor and a stack of printed circuit board (PCB) slots, one of the slots housing the line sensor and the remaining slots housing peripherals, wherein the stack of slots is covered by a dark substance. The apparatus also includes a laser harness that includes a pair of lasers for illuminating a precise line on the material along the transverse axis, the line defined by a pair of illuminated points, each point corresponding to one of the lasers. The laser harness also includes a pair of pins for precisely affixing the laser harness to the front cover by insertion in the pair of pinholes and a pair of screws for insertion in the screw holes and for locking the harness to the front cover subsequent to being precisely affixed, wherein an installation mechanism allows said front cover of the camera to be aligned to the slot that holds the line sensor. |
