Abstract:The one-dimensional continuous wavelet transform method has some advantages in hologram reconstruction, when used in the only phase, compared with the phase shifting method. This paper aims to discuss these advantages. One advantage is related to image quality. Another advantage is less power spent and saving time, because the one-dimensional continuous wavelet transform method uses only one hologram and the phase shifting method uses four holograms for recording and reconstruction processes. One final advantage is that the one-dimensional continuous wavelet transform method can also be used in real-time applications. Within the context of the ongoing optimization studies, this study will make a significant contribution to the literature because of these mentioned advantages.

“…The world of computerized holograms is roughly divided into two main types of holograms: computer-generated holograms (CGHs) 1 and digital holograms (DHs). 2 In general, SLMs are used as an interface between the electronic and optical domains and are, therefore, highly important for these two types of holograms.…”

Abstract. Today, spatial light modulators (SLMs) offer the world of digital holography a robust technology that can be incorporated into hologram recorders. This review surveys recent developments related to the role of SLMs in a family of incoherent digital hologram recorders termed Fresnel incoherent correlation holography (FINCH). Two systems branching out from FINCH, and discussed herein, are a confocal version of FINCH and a synthetic aperture FINCH-based system.

“…When this is true, group-oriented encoding can be used in place of point-oriented encoding. 9,10 But, again, group-oriented encoding suggests the need for higher-resolution pattern generators. Perhaps, rather than to direct-write each resolvable point in sequence, a reasonable compromise for this class of diffractive optic design problems is to pattern the entire group in a single processing step.…”

Fully complex diffractive optics by means of patterned diffuser arrays: encoding concept and implications for fabrication

et al. 1997

View full text Add to dashboard Cite

Arbitrary complex-valued functions can be implemented as arrays of individually specified diffusers. For any diffuser, only average step height and vertical roughness are needed to control phase and amplitude. This modulation concept suggests potentially low-cost fabrication methods in which desired topographies are patterned by exposing photoresist with partially developed speckle patterns. Analyses and experimental demonstrations that illustrate the modulation concept and aspects of the fabrication method are presented, with particular emphasis on limitations of complex recording set by various photoresist and exposure properties. Applications of diffuser array concepts to spatial light modulators and to gray-scale lithographic printing of micro-optics are also mentioned. © 1997 Optical Society of America [S0740-3232(97)
