Microscope AFM en régime de non-contact(NC) avec détection par modulation de fréquence. Dans ce type d’instrument, la sonde oscille à sa fréquence propre de l'ordre de 40 kHz. Lorsque la sonde se trouve à proximité immédiate d’une surface de référence, les effets des forces de Van der Waals modifient légèrement cette oscillation. La détection de ces modulations permet de desceller la structure subnanométrique de la surface de référence(l'échantillon). Sont inclus des scanners à tube piezo pour le NC-AFM avec amplificateurs haute tension. 2, record 2, French, - microscope%20%C3%A0%20force%20atomique%20en%20mode%20non%2Dcontact

El microscopio de fuerza atómica o AFM por sus siglas en inglés, muestrea la superficie mediante una punta muy pequeña de unos pocos micrones de largo y un diámetro más pequeño aún, de unos diez nanómetros. [...] Las fuerzas que actúan sobre el cantilever son varias. Una de ellas es la fuerza de Van der Waals que ocurre entre átomos. Esta fuerza puede ser de atracción o de repulsión, dependiendo de la distancia entre los átomos. Esto da lugar a dos modos de operación, el modo con contacto y modo sin contacto. En el modo con contacto el cantilever se sitúa a unos pocos angstroms de la superficie y la fuerza interatómica es de repulsión. En el modo sin contacto la punta se mantiene a decenas o cientos de angstroms de la superficie y las fuerzas son de atracción. 2, record 2, Spanish, - microscopio%20de%20fuerza%20at%C3%B3mica%20en%20modo%20sin%20contacto

Rate gyro: Principles of Operation. The Crossbow DMU [dynamic measurement unit] contains three accelerometers and three angular rate gyros. The three angular rate gyros use vibrating piezoelectric ceramic transducers to measure the Coriolis acceleration. In the 1830's G.
