Methodological Heterogeneity in Profilometric Assessment of Experimentally Demineralized Enamel as a Model of White Spot Lesions: A Systematic Review [PDF]
Journal of Functional BiomaterialsIntroduction: White spot lesions (WSLs) are early enamel demineralization lesions associated with increased surface roughness and plaque retention. Profilometry is commonly used to evaluate these surface changes, although methodological variability ...

Micro-Ellipso-Height-Profilometry [PDF]
Optics Communications, 1991 A new instrumental concept for surface measurement is described. In Micro-Ellipso-Height-Profilometry three independent profiles h(x), ψ(x) and Δ(x) of a surface are measured from one diffraction limited scanning spot. The basic equations for the extraction of these three quantities are derived and first results are discussed.

Pyrolyzed Photoresist as a Continuous-Tone Mask for Grayscale Lithography. [PDF]
Adv Sci (Weinh)True grayscale contact photolithography masks are created by pyrolysis of 3D multiphoton resist patterns. The resulting carbon masks retain micrometer‐scale patterned features while providing continuous‐tone optical transmission. This approach provides access to high‐quality grayscale lithography without requiring exotic materials or commercial mask ...
