Laser and electro‐optic based sensors

Looks at complex applications for lasers, optics and electro‐optics, including use in areas such as inspection and measurement. Features ESPI (electronic speckle pattern interferometry) systems and their use in the automotive industry and presents a case study involving specialist systems used in areas such as measuring print rollers and inspecting engine cylinder walls. Touches on other new techniques in the field such as chemical imaging and the recent use of Doppler vibrometry to quantify pure bending vibrations in rotating components.
