Abstract

Spectral imaging, which integrates intricate spectral analysis with spatial data, is often limited by the cumbersome and costly nature of traditional spectral sensors that include complex mechanical parts. In this study, we tackle the precision issues in compact hyperspectral imaging through the creation of a broadband spectrometer using Ta2NiSe5/ReSe2 van der Waals heterostructures. This innovative design leverages drain-source voltage adjustments to modulate the spectral response, enabling the development of a highly compact spectrometer and hyperspectral imager that obviates the need for separate optical elements. Our findings underscore the potential of van der Waals heterostructures to redefine benchmarks for optical devices and substantially enhance hyperspectral imaging technology.
