Abstract

What follows is a description of a simple apparatus for optical spectroscopic signal processing. This apparatus may be best suited for application in background interference limited emission spectroscopy for selective species detection. Operation is based on the established techniques of linear incoherent optical signal processing (OSP) (1) and optimal weight function estimation techniques (2, 3). The spectroscopic processor is made up of four components: an element to disperse the wavelength-dependent information into space-dependent information, a spatially variant optical transmission mask to filter the spectroscopic information, optical and/or electronic elements to spatially integrate the transmitted intensity and convert it to an electronic signal proportional to integrated intensity, and an electronic postprocessor to perform simple algebraic computations.
