Polarization conversion cube-corner retroreflector

Structured light production with the use of polarization interferometer

“…The resulting structure of the reflected beam polarization depends on which of the six sectors the beam hits (Fig. 1 (a)), incoming beam polarization and CCR parameters [1][2][3][4][5][6]. The wavefront of the incoming beam is divided into six parts upon its reflection from the CCR, as mentioned earlier, and these parts have different polarization states and phase shifts.…”

“…Previously, lots of work was done on creating of the cube-corner reflectors (CCR) with a certain far-field diffraction pattern, with one of the effective ways to optimize it was using a special phase-shifting interference coating to create the required phase shift of the light is reflected on the cube-corner reflectors faces. [1][2][3][4][5][6] The primary goal of developing such cube-corner prisms was related to the task of measuring the distance from the ground to satellites. Today all GPS satellites, all Glonass satellites and many other satellites are equipped by the panels, containing several dozens or even several hundreds of special CCR elements.…”

Spatial energy characteristics of glass geodetic satellites

“…where Φ is the power of the beam that is incident on the RSS and S is the cross-sectional area of the RSS. The energy characteristics of retroreflector satellites are usually described using the concept of cross-section (CS), 1,[11][12][13][14] and the CS should reach its maximum at the angle of velocity aberration of a satellite. The following equation is used to calculate CS (m 2 ):…”

Formation of polarization-symmetrical beams using cube-corner reflectors

“…The far-field diffraction pattern depends on such CCR parameters as its size, reflecting properties of faces, angle between faces, and so on, as well as on the incident light's polarization state [9][10][11][12][13][14]. One efficient way of modifying the diffraction pattern is based on controlling the phase shift δ δ s − δ p between the components of E during light reflection at the CCR faces by means of their interference coatings.…”

“…Diffraction polarizing optical elements (DPOEs) [2,9], which produce different diffraction patterns for components of the electric vector E, are especially interesting. The cube-corner reflector (CCR) represents one such DPOE [9][10][11][12][13][14].…”
