Abstract
In this manuscript, it is presented 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.
