Microwave imaging with crossed linear arrays
Soneira Ferrando, M. José; de los Reyes, Elías; Bolomey, Jean Charles (1987-11-11)
Article
Accés obertThe capabilities of a microwave imaging system working in air using two crossed linear arrays are described. The analytic expressions of the focusing procedures are derived, resolution and available volume of reconstruction ... -
Morphology-based automated baseline removal for raman spectra of artistic pigments
Pérez Pueyo, Rosanna; Soneira Ferrando, M. José; Ruiz Moreno, Sergio (2010-06)
Article
Accés obertThe interpretation of a Raman spectrum is based on the identification of its characteristic molecular bands. However, the assignment of the vibrational modes is often compromised by the presence in the spectrum of an intense ... -
Practical identification of cobalt-based blue pigments detecting the induced photoluminescence by a He-Ne laser using a Raman spectrometer
Ruiz Moreno, Sergio; Soneira Ferrando, M. José; Pérez Pueyo, Rosanna (2024-02)
Article
Accés obertSince the early 19th century, the pigment historically known as cobalt blue has been one of the most widely used in artistic painting. Its many and excellent properties led to the rapid development of different synthesis ... -
