The 3D-HAD project works towards improving the state-of-the art light-field display technology.

Nowadays, there is still a wide gap to overcome in order to market such displays as consumer ready, due to resolution limitations and other issues. Such are the aims of this project, which evaluates and proposes new approaches, based on the MIT Tensor Display, which consists of a series of LC layers stacked. By decomposing the light-field information into such layers, it is possible to represent volumetric information in a compressive way. However, there are multiple technical barriers that still need to be studied. Taking advantage from our novel 3D capturing technology, we are able to close the capture-display cycle, offering an unique and novel solution, while positioning us in the state-of-the-art of light-field display.

“Inspired by the latest advances in 3D imaging, we aim to provide new and original ways to take advantage from light-field technology. Our capture systems now enable us to easily feed such displays with real-time 3D information.”.
Jose Manuel Rodriguez: Co-founder

Following this approach, we have explored several alternatives, such as its use as a privacy screen, were it is possible to selectively display information depending on the user visualizing the system. Noteworthy, we had to take into consideration the correlation between the displayed information in order to reduce the requirements of the system to achieve a feasible state, as current technology is limited in terms of resolution and refresh rate.

Also, we designed a full calibration frame that enables us to perform not only small adjustments to the system in order to align the layers, but also to achieve novel configurations, allowing different and new approaches on light-field display.

By synthesizing the ligh-field, we are able to produce the a set of images corresponding to each of the layers of the system. Displaying them allows the observer to perceive the 3D information.

Layer 1

Layer 2

Layer 3

We built a prototype consisting in a three LCDs layer stack. Each layer support was dessigned to have a six-degree of freedom in order to be adjusted. With this, we aim not only to provide the best allignment possible, but also to test new configurations on the go.
