“…Aso, it enables simple elements replication in order to form both spherical and aspherical wavefront sets, making diffractive optic's elements useful for different applications. The majority of studies consider diffractive optical elements either as additional elements for the compensation of aberrations of a refractive imaging system [4,5], or as elements for focusing on a particular area [4][5][6][7][8][9][10][11][12][13][14]. For example, in [6,7] longitudinal intensity distribution for a coherent case is considered, [8] considers the process of a plane wave focus using a Fresnel lens, and [9] researches methods of compensation of DOE chromatic aberration.…”

Abstract. The paper presents a feasibility study for an optical system, based on a diffractive membrane. The authors have analyzed structural design of diffractive optical elements for space application and developed finite element models of diffractive lens's carrier and mount. The models were developed for two different schemes: MOIRE project and for the original scheme, developed by the authors. The schemes were analyzed for structural stiffness of the diffractive lens's carrier and mount. The shapes and frequencies of natural oscillations of the carriers of the lens were calculated. The problems of the membrane system's orbit injection and operation were analyzed. An algorithm for the terminal control of the orbital period, eccentricity and longitude of the point of standing of the orbital surveillance system was proposed.Keywords: diffractive optics, space membrane optical system, finite element modeling, space telescope, geostationary orbit Citation: Salmin VV, Karpeev SV, Peresypkin KV, Сhetverikov AS, Tkachenko IS.

“…In principle, any dispersive device could be used as the chromatic objective, such as diffractive lenses (Dobson 1997, Lin 1998 or dynamic wavelength tuning systems. However, the quality of the dispersion and the cost of non-conventional objectives rules out their use in commercial systems.…”

Abstract. Chromatic confocal probes are single point optical sensors built around a confocal coaxial setting that use chromatic dispersion and decoding to obtain the surface distance. Such sensors are usually installed on scanning stages of surface texture measuring instruments, roundness instruments or coordinate measuring machines. Chromatic confocal probes can measure on, and through, transparent material, detect several interfaces between materials and, therefore, calculate thickness. The metrological characteristics of chromatic confocal probes are close to those of stylus probes and they are often used as a non-contact substitute on stylus profilometers.

“…Furthermore, they enable the formation of light beams with properties that can not otherwise be obtained by classical optical refractive elements. However, DOE are characterised by significant chromatic aberration, which can have both negative and positive impacts upon the imaging system [1][2][3][4][5][6][7][8][9][10].…”

Abstract. This work is devoted to the study of the axial image point formed by a layered diffractive lens illuminated by laser light of different wavelengths. The influence of chromaticity can be identified when there is a change of quantisation levels and harmonic interval (bringing the phase to the level 2πn). The influence of aberrations introduced in the form of converging or diverging conical and cubic wavefronts will also be considered in this study. Keywords: diffractive optical elements, aberrations, chromatic properties of lensCitation: Kovalenko AI. Study of the chromatic properties of harmonic diffractive lens.
