Leith and Upatnieks proposed multicolor wavefront reconstmction and Denisyuk introduced the single-beam reflection holography technique which is most suitable for recording color holograms today. Reviewed is the history of color holography highlighting important milestones. The current state-of-the-art of color holography is presented including the recording techniques using red, green and blue laser wavelengths. The laser wavelength selection issue is presented using computer simulation, showing that more than three wavelengths may be needed for accurate color rendition in holograms. The recording material is a key factor very important for creating high-quality color holograms. Covered are both the demand on the material and suitable products currently on the market. The future of color holography is highly dependent on the availability of improved panchromatic recording materials and suitable light sources for displaying the holograms. Small laser diodes as well as powerful white LEDs and OLEDs with very limited source diameters are important for color holography to become an important 3D display medium.","PeriodicalId":266048,"journal":{"name":"International Conference on Holography, Optical Recording, and Processing of Information","volume":"71 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130229676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applications include imaging and display of three-dimensional (3D) objects, and encryption and pattern recognition of two-dimensional (2D) and 3D objects. Often, these optical systems employ discrete spatial light modulators (SLMs) such as liquid-crystal displays. In the 2D case, SLMs can encode the inputs and keys during encryption and decryption. For 3D processing, the SLM can be used as part of an optical reconstruction technique for 3D objects, and can also represent the key during encryption and decryption. However, discrete SLMs can represent only discrete levels of data necessitating a quantisation of continuous valued analog information. To date, many such optical systems have been proposed in the literature, yet there has been relatively little experimental evaluation of the practical performance of discrete SLMs in these systems. In this paper, we characterise conventional phase-modulating liquid-crystal devices and examine their limitations (in terms of phase quantisation, alignment tolerances, and nonlinear response) for the encryption of 2D and 3D data. Finally, we highlight the practical importance of a highly controlled discretisation (optimal quantisation) for compression of digital holograms.","PeriodicalId":266048,"journal":{"name":"International Conference on Holography, Optical Recording, and Processing of Information","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127291106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
