Chromatic confocal metalens and scattering medium-based speckle pattern engineering for compact, low-cost distometers

Chromatic confocal metalens and scattering medium-based speckle pattern engineering for compact, low-cost distometers
Chromatic confocal metalens and scattering medium-based speckle pattern engineering for compact, low-cost distometers
We demonstrate a reconstructive distometer with 0.78 micron resolution and 2.5 cm cubic footprint, utilising an engineered metalens and laser-written scattering medium for tailored speckle pattern generation, benefiting from low-cost, compact size and high stability.

Abstract

We demonstrate a reconstructive distometer with 0.78 micron resolution and 2.5 cm cubic footprint, utilising an engineered metalens and laser-written scattering medium for tailored speckle pattern generation, benefiting from low-cost, compact size and high stability.
