Electronics and Photonics Research Institute, National Institute of Advanced Industrial Science and Technology, Tsukuba, Japan
J Opt Soc Am A Opt Image Sci Vis 29:1288-92. 2012..From the measurement data, the object can be reconstructed using standard phase retrieval algorithms...
- Liquid-crystal adaptive optics based on feedback interferometry for high-resolution retinal imagingTomohiro Shirai
Photonics Research Institute, National Institute of Advances Industrial Science and Technology, Tsukuba, Japan
Appl Opt 41:4013-23. 2002..We observed that an image of the test target (mimicking a retina) blurred by the aberration plate (mimicking ocular aberrations) was successfully restored immediately after our adaptive optics system was activated...
- Visibility in ghost imaging with classical partially polarized electromagnetic beamsTomohiro Shirai
Electronics and Photonics Research Institute, National Institute of Advanced Industrial Science and Technology, 1 2 1 Namiki, Tsukuba 305 8564, Japan
Opt Lett 36:2880-2. 2011..Hence, a polarized beam is superior to an unpolarized one to obtain a high-visibility ghost image. Some related issues in recent literature are also addressed...
