Abstract
A method for processing and/or analyzing image information representing radiation in a spatially resolved manner using an optical system coupled to at least one detector includes the step of collecting said image information with said optical system using at least one micromechanical mirror moved such that the image information is scanned and coupled sequentially into the at least one detector.

A method for monitoring an industrial combustion process wherein comprising processing and/or analyzing image information, image information represents a represents a the two dimensionally spatially resolved emission spectrum of a flame resulting from a combustion process in a combustion chamber, the method comprising:
- collecting the image information by an optical system having at least one micromechanical mirror, which is mechanically variably tiltable, such that the image information is scanned by the mirror
- coupling the image information sequentially into the at least two detectors, wherein the optical system includes a lens and a fibre bundle with optical fibers, and the at least one micromechanical mirror is arranged behind a window of the combustion chamber to separate the chamber from space in which the mirror is located;
- coupling the image information received from the micromechanical mirror into a first end of the fiber bundle as an optical signal;
- transmitting, via a second end of said fiber bundle coupled to the at least two detectors, the image information to the at least two detectors, each of the detectors being connected to a dedicated fiber and being sensitive to a certain frequency range for detecting organic radicals in order to characterize the combustion process in an analyzing unit, and
- providing measured parameters from the analyzing unit as input data to a control circuit, and the control circuit controlling the supply of fuel or any other combustion material or combustion air.
