Abstract:
A laser alignment tool includes a line laser assembly including a laser and emitting a laser beam line and an electronic target assembly including a photo detector array. The laser beam line of the laser is pointed toward the center of the photo detector array with the longitudinal axis of the laser beam line being perpendicular to the centerline of the photo detector array. The line laser assembly includes a laser diode having a line-generating lens attached in front using a lens holder and being mounted onto a tilt stage. Using a line laser provides a certified accuracy of +/-0. 005 inches at a distance of 10 feet. The electronic target further includes a narrow band pass filter and a discrete LED display that is controlled by a microprocessor. The microprocessor may be programmed with a variable range for each LED of the discrete LED display according to the alignment task.
