Diffraction lens in imaging spectrometer

Abstract

Abstract. А possibility of using a diffractive lens as the simplest imaging spectrometer was considered. An experimental construction of the spectral imaging for white, red and green LEDs was conducted. When processing the images the influence of the scattered components of the initial point and nearly points of the image was taken into consideration. There was made a comparison of the received spectral distribution with the spectra of these LEDs, received by means of spectrometer. Root-mean-square error (RMSE) from 8 to 13%.Keywords: diffraction lens, imaging spectrometer, spectral image. Citation: Blank V.A., Skidanov R.V. Diffraction lens in imaging spectrometer.
