Abstract
A novel scheme for making absolute wavelength measurements with a grating spectrograph is proposed. A grating with special multiple rulings is illuminated with a reference laser of known wavelength to project a ruler-like diffraction pattern of equidistant wavelength calibration lines directly onto the unknown spectrum.
