Abstract: (844 Views)
In this paper, the advantages of using concentric circular diffraction grating with equal spaces compared to linear diffraction grating in smartphone-based methods are investigated. Their image-formation properties are described, and we examine the effects of linear and circular diffraction grating aberrations for spectrometer-based smartphones. Data collection is done by the smartphone camera, so we need to have the image with the least amount of aberration and the highest image quality. With circular diffraction gratings, the curvature of the field, the distortion aberration, and the wavefront aberration are reduced. Therefore, the most suitable system for making this type of spectrometer is the use of circular diffraction gratings.
