Colour matching on-a-chip

Grant number: LP160100959 | Funding period: 2016 - 2019

Completed

Abstract

This project aims to develop a small, lightweight and low cost chip for accurate spectral measurements, using recent advances in nano-optics. Optical spectrometers are widely used in science and industry but are large, heavy and expensive. The new chip could enable hand-held devices with performance comparable to large laboratory instruments. It could be revolutionary for colour matching, i.e. determining the colours of materials, offering unprecedented accuracy and robustness to illumination conditions given the size, weight and cost of the device. This technology is anticipated to foster the development of new products using the chip; and make Australia a leader in nano-optics research.
