Description
Holography presents a basis for applications in imaging, measurements and displays; however, the achieved image quality in the replay field poses challenges to computer-generated holography. In a computer-generated holographic projection system, the image is generated via diffraction of light from spatial light modulators. In this process, several factors contribute to non-linearities between the replay field and the target image. The images in this dataset were captured to demonstrate the effectiveness of gamma correction method in holographic projection.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
