Research data supporting “Gamma Correction in Holographic Projection"


Change log

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.

Image descriptions:

  1. "Replay field of holographic projection of linear ramp.jpg": Holographic projection replay field of linear grey-scale ramp.
  2. "Replay field of holographic projection of gama corrected ramp.jpg": Holographic projection replay field of gamma corrected grey-scale ramp.
  3. "Replay field of holographic projection of uncorrected city scene.jpg": Replay field of Sample image of city scene before gamma correction.
  4. "Replay field of holographic projection of gamma corrected city scene.jpg": Relay field of Sample image of city scene after gamma correction.
  5. "Replay field of holographic projection of uncorrected horse.jpg": Replay field of Sample image horse before gamma correction.
  6. "Replay field of holographic projection of gamma corrected horse.jpg": Replay field of Sample image horse after gamma correction.

The device used to capture the images was a Digital single-lens reflex camera of Model Cannon EOS 550D.
