Holography is a technique to record and reconstruct three dimensional (3D) information
without mandating lenses. Digital holography (DH) provides direct access to the complex …

Holographic interferometry is a well-established field of science and optical engineering. It
has a half-century history of successful implementation as the solution to numerous …

A novel radius of the curvature measurement method for optical spherical surfaces using
absolute interferometry is proposed. A measurement setup is designed and built around a …

Errors that occur when surface topography is measured and analysed can be classified
depending on the type of surface studied. Many types of surface topographies are …

Abstract Roll‐to‐Roll (R2R) manufacturing is changing how state‐of‐the‐art technology is
made. Roll‐to‐Roll is part of a family of advanced scalable inline manufacturing techniques …

Digital holography (DH) is a promising method for non-contact surface topography because
the reconstructed phase image can visualize the nanometer unevenness in a sample …

Abstract Machine tools are integral part of the machining process and they require regular
monitoring for detection of wear of the tool to control the surface finish of the machined …

The shape of the tympanic membrane (TM) plays an important role in sound transmission
through the ear for hearing. Previously we developed a high-speed holographic system …

A study of surface topography can provide valuable information on the product. Since the
material finishing relies on the measured topography, the manufacturing process can be …

This paper presents analytical modeling of the speckle decorrelation noise in digital Fresnel
holographic interferometry. The theoretical analysis is carried out by considering the …
