Resumen:
Optical aberrations can greatly distort the image created by an optical
element. Several aberrations can affect the image simultaneously and
discerning or visualizing specific aberrations can be difficult. By
making use of an optically levitated droplet as a light source, we have
visualized the spherical aberration and coma of a lens. The droplet
approximates a point source in the ray optic regime but, at the same
time, creates a diffraction pattern in the far-field region similar to
that used in the Ronchi test. When focused by a lens, this micro double
point source creates patterns that resemble comets, barreling,
hyperbolic triangles, and, most strikingly, a spider. We show how all
these patterns are a consequence of spherical aberration and coma. The
Zernike polynomials were used to quantify the value of several
individual aberrations by comparing them to patterns resulting from
numerical simulations. (C) 2020 Optical Society of America under the
