Optical alignment II; Proceedings of the Meeting, Arlington, VA, May 3, 4, 1984

Subjects related to alignment theory are examined, taking into account alignment theory and practice for diffraction grating rhombs, a three wavelength optical alignment of the Nova laser, techniques for characterizing optical system fabrication, and the development of a multidetector deflection measurement system. Alignment systems and problems of active alignment are also considered, giving attention to electronic coordinate determination, a device which sets a new standard for precision measurement in nongravitational environments, an infrared alignment telescope, a laser alignment control system, an automatic alignment station for single or multimode optical fibers, and an automatic assembling station for guided optic components. Alignment techniques are discussed. Point-diffraction interferometry as a diagnostic for alignment is considered along with the alignment of earth-scanning mapper telescopes and test collimators using computerized signal histogram printouts, and the alignment and collimation of submarine periscope optics.
