METHOD AND APPARATUS FOR ANALYZING FILTER PERFORMANCE IN REAL TIME USING OPTICAL MEASUREMENT METHOD

摘要

A method and apparatus for analyzing real-time filter performance using an optical measurement method are presented. According to an embodiment, a method for analyzing real-time filter performance using an optical measurement method includes: transmitting an optical signal using a diode laser to a filter of a measurement test unit through which a measurement target gas flows; Acquiring an optical signal generated by the diode laser; Decomposing an absorbed signal from a change in the optical spectrum of the obtained optical signal; Recording the intensity of the absorption signal for each concentration through a calibration test in the presence of gas flow before and after the filter; And estimating a concentration of the measurement target gas before and after the filter from a change in an absorption spectrum obtained by recording the intensity of the absorption signal for each concentration.
