Beschreibung
Zusammenfassung:	A method for monitoring an additive manufacturing process during fabrication of a component part is disclosed. In various embodiments, the method includes the steps of selecting a sensing matrix; orienting a sensor toward a surface of the component part; generating a discrete time signal, based on data obtained from the sensor, the discrete time signal being representative of a process condition of the component part while the component part is undergoing the additive manufacturing process; compressing the discrete time signal using the sensing matrix to form a compressed measurement signal; and storing the compressed measurement signal in a storage device while the component part is undergoing the additive manufacturing process. In various embodiments, selecting the sensing matrix comprises selecting a basis function. In various embodiments, the basis function is determined using a random time sampling.
