Optical corrector of deviations of laser emitter array linear direction

摘要

The corrector has an array (32) of the laser emitters (34-39) which are aligned in a direction along the array so that the emitter positions in a direction orthogonal to array longitudinal direction deviate from linear directions along the array. Each laser emitter generates a light beam propagating orthogonally to the longitudinal and transverse direction such that light beams propagate along separate light beam paths, in which is located a corrector (42), aligning the light beam paths in a direction transverse to the array for correction of laser emitter deviations from the linear, longitudinal array direction.
