Congratulations to the winners of OPN’s 11th annual After Image photo contest.

A droplet of fluorescent molecules sits atop an array of nano-scale holes. An excitation laser from below is diffracted by the nanohole array, causing a bloom of internally reflected fluorescence within the droplet. The fluorescence from this array was used to calibrate the field-dependent aberrations of a super-resolved fluorescence microscope

“Acoustic waves spectrally modulate supercontinuum light inside an acousto-optic tunable filter. The supercontinuum light interacts with resonating acoustic modes to produce four-lobed orange, green and rainbow Schaefer-Bergmann diffraction patterns around the two spectrally modulated beams and undiffracted light. These optical patterns can quantitatively measure acoustic properties of crystals.”
