We propose a system that utilizes reflection holograms to realize color holography that illuminates from the back site. In this configuration, two types of polarizers and two quarter-wave plates are used. By combining these elements and controlling the polarization direction of the transmitted beam that passes through them, it is possible to avoid the drawbacks of the conventional method of illuminating from the front.

Article Synopsis
  • Electro-holography struggles with narrow visual field angles due to the limited resolution of spatial light modulators, affecting the display of fringe patterns.
  • A new projector-type electro-holographic compact display is proposed, utilizing a combination of advanced optical systems and calculation algorithms to significantly enhance the visual field angle.
  • Experimental results indicate that this new system achieves a visual field angle that is three times larger than standard electro-holographic displays, while also accurately presenting full-color, high-resolution 3D images with depth perception.

Humanin (HN) is a 24-residue peptide that manipulates cell survival under various stresses. A highly potent HN derivative, HNG, reduced amyloid burden and neuroinflammation and suppressed cognitive impairment in Alzheimer's disease model mice. Cuprizone (CPZ), a copper chelator, provokes demyelination in the central nervous system of mice.

Humanin (HN) is an endogenous 24-residue peptide. A highly potent HN derivative, S14G-HN, which has a substitution of serine 14 to glycine, reduced amyloid burden and suppressed cognitive impairment in a mouse model of Alzheimer's disease. S14G-HN also suppressed amnesia induced by a muscarinic receptor antagonist in rodents.
