Simple and automatic wavelength calculation with a machine vision camera, by measuring the diameter of an Airy disk
Year: 2024
Type: conference-paper
Abstract: This work presents a simple and automated educational resource with the aim of determining the wavelength of a laser source that uses the Airy disk generated by a circular aperture. It is known that there is a relationship between the diameter of the central disk and the distance between the circular aperture and the image plane. These two parameters are automatically measured by using a machine vision sensor and an ultrasonic distance sensor, respectively. This resource can be applied in graduate or undergraduate Physics and Engineering laboratories and classrooms for educational, demonstrative, or measuring purposes.
