Abstract

Filter-free color imaging is the long-pursued solution for its simple structure, low cost, and high stability. However, a spectroscopic unit is still necessary for the current Si-based imaging unit due to the intrinsic photoresponse properties of Si. Here, the authors demonstrate a filter-free color-resolved single-pixel imaging (SPI) by combining the working mechanism of computational ghost imaging and the response characteristic of perovskite. Benefitting from a broad linear dynamic range (106.5 dB) and a high detectivity (4.03 × 10 Jones) of the fabricated ultrasensitive MAPbBr microwire arrays (MWAs) photodetector, the light attenuation caused by an object can be effectively correlated with its color. The reconstructed images of both transmissive and reflective color objects show a high wavelength resolution reaching 20 nm in the range of 400–540 nm, which is impossible to achieve by commercial silicon-photodiode-based ones. This work can open a new door for the image acquisition of color-sensitive objects and also pave a way for the evolution of the next generation of detectors and cameras with low-dimensional perovskite materials.
