QUÉ SIGNIFICA SPECKLE INTERFEROMETRY EN INGLÉS
Imágenes de Speckle
Imagen típica de corta exposición de una estrella binaria vista a través de la visión atmosférica. Cada estrella debe aparecer como un solo punto, pero la atmósfera hace que las imágenes de las dos estrellas se dividan en dos patrones de manchas. Las manchas son un poco difíciles de distinguir en esta imagen debido al tamaño de píxel grueso de la cámara utilizada. Las manchas se mueven rápidamente, de modo que cada estrella aparece como una sola gota difusa en las imágenes de exposición largas. El telescopio utilizado tenía un diámetro de aproximadamente 7r0. Película de proyección de lente de movimiento lento, que muestra lo que se ve a través de un telescopio cuando se mira una estrella con gran aumento. El telescopio utilizado tenía un diámetro de aproximadamente 7r0. Observe cómo la estrella se divide en blobs múltiples - totalmente un efecto atmosférico. Las técnicas de imagen de Speckle intentan recrear la imagen del objeto tal como era antes de ser corrompida por la atmósfera. Algunas vibraciones del telescopio también se notan en esta película. Speckle describe una gama de técnicas de imágenes astronómicas de alta resolución basadas en el método shift-and-add o en métodos de interferometría de speckle.
definición de speckle interferometry en el diccionario inglés
La definición de interferometría speckle en el diccionario es una técnica para aumentar la resolución angular de los telescopios que se ven afectados por la turbulencia atmosférica, en la que se combina la información de varias exposiciones de muy corta duración.

Digital
speckle pattern
interferometry and related techniques
This is an invaluable text for practising engineers in industry and research institutes, and academic and development researchers in scientific and engineering disciplines who use, or are interested in, DSPI.
The new techniques of hologram and speckle interferometry have extended
interferometry to studies of rough surfaces and of changes that occur with time.
They have now become major methods of non-destructive testing. Detailed
treatments ...
William Howard Steel,
1983
Stellar speckle interferometry [Labeyrie, 1970, 1976] is a technique which can
give, within certain limitations, diffraction-limited imaging of stellar objects, in
spite of image degradation by the atmosphere and telescope aberrations.
