title: The diffraction grating-an opinionated appraisal.
abstract: Advances in diffraction grating ruling made in the past twenty-five years are reviewed, particularly demonstrating the application of interferometry and electronics to ruling engine control. Portions of this paper were presented at the Eighth Australian Spectroscopy Conference at Monash University in August 1971, under the Geoffrey Frew Fellowship.
