Descriptor English: Second Harmonic Generation Microscopy
Descriptor Spanish: Microscopía de Generación del Segundo Armónico
Descriptor microscopía de generación del segundo armónico
Entry term(s) microscopía del generación de tercer armónico
Scope note: Técnica de microscopía que aprovecha la generación de armónicos que ocurre cuando los fotones interaccionan para generar nuevos fotones de diferente longitud de onda. En la generación del segundo armónico, dos fotones de la misma longitud de onda y frecuencia, como los de los RAYOS LÁSER, interaccionan dentro de un medio y se convierten en un fotón del doble de la frecuencia y la mitad de la longitud de onda de los dos protones incidentes. Las señales de luz capturadas se usan para producir imágenes que dependen de las propiedades ópticas únicas del material.

RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D000073798
Scope note: A microscopic imaging technique that takes advantage of the process of harmonic generation that occurs when photons interact to generate new photons of a different wavelength. In second harmonic generation, two photons of the same wavelength and frequency, such as from a LASER, interact inside a medium and are converted to a photon of twice the frequency and half of the wavelength of the two incident photons. The light signals captured are used to produce images that are dependent on the unique optical properties of the material.
