SPIEDigitalLibrary.orgPaper Numbering: Proceedings of SPIE follow an e-First publication model. A unique citation identifier (CID) number is assigned to each article at the time of publication. Utilization of CIDs allows articles to be fully citable as soon as they are published online, and connects the same identifier to all online and print versions of the publication. SPIE uses a six-digit CID article numbering system structured as follows:The first four digits correspond to the SPIE volume number. The last two digits indicate publication order within the volume using a Base 36 numbering system employing both numerals and letters. These two-number sets start with 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B … 0Z, followed by 10-1Z, 20-2Z, etc. The CID Number appears on each page of the manuscript. 9970 1K Scale estimation of objects using template matching 9970 1L Optical correlation algorithm for reconstructing phase skeleton of complex optical fields 9970 1M Methods of restoring spatial phase distribution of complex optical fields 9970 1N 2D Hilbert transform for phase retrieval of speckle fields 9970 1O Using of microparticles for coherent properties of optical fields diagnosing 1PThe interconnection of degree of coherence and Rayleigh particles velocity motion 9970 1Q Fringe-projection method for three-dimensional digitization of human faces 1SThe analysis of long-wave infrared polarization signal of typical material targets

Analysis of holographic polymer-dispersed liquid crystals (HPDLCs) for tunable low frequency diffractive optical elements recording

“…We have widely analyzed in previous studies the viability of different photopolymeric materials to record diffractive optical elements (DOEs) like lenses or blazed gratings [22][23][24]. In this case, as an extension of the results shown in [25], we continue exploring the behavior of a HPDLC material to record low frequency DOEs with different spatial periods using a Liquid Cristal on Silicon (LCoS) display working in mostly amplitude mode as a master.…”
