Researchers Achieve Record Infrared Image Resolution Using Unseen Light
A resolution of ~1460 was previously unattainable when imaging using undetectable infrared light around 1550nm. Now, spontaneous parametric down-conversion allows spectrally resolved transmission imaging without directly detecting these wavelengths, demonstrated by successfully mapping attenuation within a zebrafish larva. This silicon-based approach promises more accessible quantum sensing technologies for biology and materials science.
