title: Gaussian laser-beam-diameter measurement using sinusoidal and triangular rulings.
abstract: Gaussian laser-beam-diameter measurements using triangular and sinusoidal rulings are analyzed. The effects of periodicity and contrast are considered. For the measurement of extremely small Gaussian beam diameter these rulings are found to be more reliable than Ronchi rulings.
