Large-Angle Dot Projector

[September 17, 2019]

In VirtualLab Fusion, by connecting different field solvers, we demonstrate how a dot project works.

A large-angle dot projector is the key optical component in Apple’s Face ID, which casts a structured dot pattern onto the face so as to create a 3D facial map. The dot projection system often employs an array of VCSEL units. Light from the VCSEL array is first collimated by a lens system, and then replicated by a two-dimensional grating into a large angular range. Simulation of such systems would require an appropriate model of the VCSEL source, a dependable handling of the lens system, and a rigorous method for gratings with relatively small periods. In VirtualLab Fusion, this connection of different field solvers is par for the course; we use this ability below in a demonstration of how a dot projector works.

Tightly Focused Light

[September 02, 2019]
We demonstrate, using the software VirtualLab Fusion, how different polarization states (e.g. radial) and aperture shapes (e.g. annular) may influence the electromagnetic field in the focal region.
[September 02, 2019]

We demonstrate, using the software VirtualLab Fusion, how different polarization states (e.g. radial) and aperture shapes (e.g. annular) may influence the electromagnetic field in the focal region.

How to focus light into an ever-smaller spot is an ever-present question in the optics community. Various approaches with the aim to focus light tightly have been developed, particularly of late. Investigation of light focusing under a high-NA configuration often requires fully vectorial electromagnetic simulation techniques. We demonstrate, using the software VirtualLab Fusion, how different polarization states (e.g. radial) and aperture shapes (e.g. annular) may influence the electromagnetic field in the focal region. Such analyzes can be done either with idealized lenses, or with real lenses with explicit structure and material information.

We demonstrate, using the software VirtualLab Fusion, how different polarization states (e.g. radial) and aperture shapes (e.g. annular) may influence the electromagnetic field in the focal region.
