CHEMILUMINESCENCE IMAGING SYSTEM AND METHOD OF MONITORING A COMBUSTOR FLAME OF A TURBINE ENGINE

摘要

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.

1. A chemiluminescence imaging system comprising:
a sensor array including a plurality of pixels operable to capture an image; a multispectral mask array having a plurality of cells with each cell associated with a respective pixel and being one of a plurality of band-pass filter types with the plurality of band-pass filter types being distributed across the multispectral mask; and an attenuation filter array adjacent to the multispectral mask array and having a plurality of cells with each cell associated with a respective cell of the multispectral mask array for obtaining proper exposure of each of the plurality of pixels.
