Due to its ruggedness and often contactless characteristics, optical systems are one of the most adopted, particularly when fast changes in displacement need to be measured. Moreover, due to the physical principles that support the operation of some of those systems (e.g., optical interferometry), they allow the measurement of linear displacements with resolutions and accuracies below the nanometer. Miniaturization and mass replications have begun to lead the optical industry in the transition from traditional analog to novel digital optics. Digital optics is information optics in its maturity. It assumes using digital processing units as an integral part of optical imaging and measurement systems. Digital processors are used both for control of optical systems and for processing optical signals. One of the main use of digital signal processing in optical imaging and measuring devices is data calibration, and, in particular, data denoising.Digital Optical Measurement Techniques presents cutting-edge information on the development and application of optical techniques and laser technology in engineering.
