The Holographic Classroom

Holography has a long history as a teaching tool, from the early use as interactive 3D representations of skulls, dental molds and religious relics to the current trend of integration into mixed reality to enhance the teaching and learning process. In this article, we take a look at the evolving role of the technology in teaching and, conversely, at how educators teach students about the technology.

Light Sheet Holography – a New Class of Hologram

A team of scientists and engineers led by Federico Capasso, Senior Research Fellow in Electrical Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has reported in Nature Photonics a new way of creating holograms using threads of light layered to construct 2D sheets containing tightly controlled arrays of light. These sheets can then be tightly stacked –like a pile of cheese slices – to depict 3D objects.

Perfect Particles Make 3D Structurally Coloured Objects

The particle theory of matter sits at the centre of the scientific methodology. Objects that appear uniform, solid and homogeneous at the everyday macroscopic scale are, when you investigate them with sufficient resolution and detail, in fact made up of particles (atoms, molecules and compounds) that are not the same entity as the object they form.

Polarization Holography – a New Field of Holographic Research

In conventional holography, the polarization of the reference and object beams are arranged to be co-linear to achieve the maximum contrast of the interference fringes formed and record the greatest amounts of amplitude and phase information from the original object wave.
