Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1660. WebThe aim of this paper is to demonstrate the application of reflective diffraction grating and MWIR thermal camera for identification of gas and estimation of its concentration.

WebIn general, the PGA sensors can detect nine diffraction orders of phase grating [9,10]. The diffraction light of the odd orders (DLO) is useful to calculate the measurement positions. However, the diffraction light of the zeroth and the even orders (DLZE) is the main contributor of stray light which greatly deteriorates the signal quality. Webdiffraction orders may disappear, although they fulfil the former interference condition. For instance, the simplest binary amplitude diffraction grating, where the width of the slit is half the period of the grating, produces a diffraction pattern where all even diffraction orders are missing.
