Abstract: A chemiluminescence imaging system that may be used for monitoring a combustor flame of a gas turbine engine includes a sensor array having a plurality of pixels operable to capture an image. A multispectral mask array and an attenuation filer array of the system may be generally placed in front of the sensor array and each have a plurality of cells that are generally align, respectively, to the plurality of pixels. Each cell is generally one of a plurality of band-pass filter types distributed randomly across the multispectral mask array and an image reconstruction algorithm is used to produce at least one image for evaluating properties of the flame.

Abstract: A method and system for performing automated defect detection is disclosed. The system may include at least one database, an image capture device and a processor. The method may comprise providing at least one database for storing information used in processing data to detect a defect in at least one member of a plurality of members in a device. The information may include a plurality of different modes of data. The method may further comprise providing a processing unit for processing the information; receiving, by the database, updates to the information; identifying a potential defect in a first mode of data; applying, by the processing unit, analysis of a second mode of data, the analysis of the second mode of data triggered by the identifying, the second mode of data different than the first mode of data; and reporting defects based on the results of the applying.
