dc.description.abstractCylindrical lenses are promising devices for a wide range of applications [1-3]. This kind of lenses can be used in some novel applications such as light-sheet microscopy, line illumination microscopy or autostereoscopic devices. However, as any kind of lens, the main drawback is the generation of optical aberrations. These aberrations determine the image quality of an optical system. Interferometrists often like to represent wavefronts as Zernike polynomials. Zernike polynomials have been widely used because, unlike other polynomial set, they are orthogonal over a unit circle and represent balanced classical optical aberrations, yielding minimum variance over a circular pupil [4]. These characteristics are lost when non circular pupils are employed. Some research works have developed new coefficients for different pupils [5]. Notwithstanding that, they were targeted for rotational symmetric optics [6]. In the referred paper, 2D Chebyshev polynomials related to some Seidel aberrations are described. These ones form a useful orthogonal basis for optics of rectangular apertures, making them an attractive option for cylindrical lenses. In this work, optical aberrations in a liquid crystal (LC) cylindrical lens have been modeled and measured, for the first time. We have developed our own application specifically to extract the 3D wavefront from an interference pattern. This software tool also allows us to obtain the optical aberrations based on Chebyshev polynomials. A tunable LC cylindrical lens has been designed and manufactured. Optical aberrations have been assessed by adjusting the control voltage applied to the device.en
