Abstract
A corner cube retroreflector (CCR) consists of three perpendicular flat surfaces and reflects the incident light back to its source.

A corner cube retrore ector (CCR) is an optical device that re ects the light back to the source.[1,2] Directional properties of the CCR are due to the total internal re ection (TIR) from its three orthogonally placed mirror surfaces,[3,4] and have found applications in various elds, such as navigation, displays, image processing, free-space communication, and sensors etc.[4,5,6,7,8,9,10,11] It is not always desirable to make perfect CCRs
We suggest that the diffraction intensity variation was due to the response of internal multi-grating structure (AgBr NCs) of the hologram and their interaction with respect to monochromatic light
Summary
CCRs including microelectromechanical, lithography, and direct laser writing.[13,14,15] Diamond micro-maching was used to directly cut 120 CCR faces for high retrore ection.[16]. Holography technique with desired surface functionalities have been recently reported to produce CCRs and other optical device (lens, diffuser, 1D/2D patterns, and diffraction grating, etc.), which is a simple, fast, and cost-effective process.[21,22,23]. A CCR array hologram is recorded on a light sensitive ORM through Denisyuk re ection holography method. Optical properties of the recorded hologram were studied using re ection, diffraction, rational, and far- eld experiments, as well as, by computational modelling. Far- eld experiments showed bright and well-resolved 2nd order diffraction patterns with monochromatic light (red, green, and blue) illuminations. The CCR array hologram showed angular dependence of white light re ection and exhibited a color resolved diffraction when subject to a broadband illumination. Image projection experiments were carried out to study the rotational property of the CCR array hologram
