“…In 2017, Su and Yuan [16] proposed a method called effective perspective image segmentation and mosaicking (EPISM) method to simulate two-step method by a single-step process. Further research on the EPISM method was carried out by Su and Yan [17][18][19] to improve image quality and printing efficiency. In addition, many researchers have made valuable research in recent years [20,21].…”

Effective perspective image segmentation and mosaicking (EPISM) method is an effective holographic stereogram printing method, but a mosaic misplacement of reconstruction image occurred when focusing away from the reconstruction image plane. In this paper, a method known as holographic element-based effective perspective image segmentation and mosaicking is proposed. Holographic element (hogel) correspondence is used in EPISM method as pixel correspondence is used in direct-writing digital holography (DWDH) method to generate effective perspective images segments. The synthetic perspective image for holographic stereogram printing is obtained by mosaicking all the effective perspective images segments. Optical experiments verified that the holographic stereogram printed by the proposed method can provide high-quality reconstruction imagery and solve the mosaic misplacement inherent in the EPISM method.

“…Con el desarrollo de las tecnologías digitales se han propuesto diferentes técnicas para sintetizar hologramas de escenas que pueden ser virtuales o físicas. [8][9][10]. Comparados con la holografía clásica, los hologramas sintéticos utilizan imágenes 2D para almacenar la información tanto de objetos físicos como de escenas creadas en computador.…”

“…Comparados con la holografía clásica, los hologramas sintéticos utilizan imágenes 2D para almacenar la información tanto de objetos físicos como de escenas creadas en computador. Por su posibilidad para obtener hologramas de objetos que no pueden registrarse analógicamente y su capacidad para integrar tecnologías computacionales, la holografía sintética ha permitido que la holografía como sistema de exhibición 3D se use ampliamente en un ámbito comercial en sectores como la arquitectura, el sector militar, automotriz, médico y el entretenimiento [2,5,7,9].…”

“…Los EHs comparados con los HGCs no requieren de ningún cálculo complejo de difracción para obtener la información de la escena 3D, por lo que el costo computacional se reduce significativamente y adicionalmente, presenta la ventaja de obtener la información de las escenas 3D de manera directa a partir de cualquier software de computación gráfica 3D [11]. Gracias a su alto impacto visual y su capacidad para reducir la cantidad de información requerida en su registro, esta técnica ha sido ampliamente utilizada por grupos de investigación y empresas en el sector académico y comercial [7,9,16,17].…”

Holoprinters based on holographic stereograms (HS) have been developed to synthesize holograms by using 2D images with perspective information of 3D objects. The objects can be real or computer generated. HS has been applied to different fields such as engineering, medicine and military because the high visual impact of the tridimensional and multi-view images it presents. To implement a Holoprinter requires development of three components: i) 2D images generation, ii) optical system design for HS recording and iii) mechanical and control implementation. Therefore, we design and develop each of the components, which integrated compose a holoprinter to synthesize full parallax HS. This paper studies basis for production of this kind of holograms and describes the computational and opto-mechanical design and implementation that we have made. Experimental HS were obtained to validate the system.

Driver's access to information about navigation and vehicle data through in‐car displays and personal devices distract the driver from safe vehicle management. The discrepancy between road safety and infotainment must be addressed to develop safely operated modern vehicles. Head‐up displays (HUDs) aim to introduce a seamless uptake of visual information for the driver while securely operating a vehicle. HUDs projected on the windshield provide the driver with visual navigation and vehicle data within the comfort of the driver's personal eye box through a customizable extended display space. Windshield HUDs do not require the driver to shift the gaze away from the road to attain road information. This article presents a review of technological advances and future perspectives in holographic HUDs by analyzing the optoelectronics devices and the user experience of the driver. The review elucidates holographic displays and full augmented reality in 3D with depth perception when projecting the visual information on the road within the driver's gaze. Design factors, functionality, and the integration of personalized machine learning technologies into holographic HUDs are discussed. Application examples of the display technologies regarding road safety and security are presented. An outlook is provided to reflect on display trends and autonomous driving.
