Image scanning microscopy (ISM) with a single photon avalanche diode (SPAD) array detector
Optics, Photonics, and Digital Technologies for Imaging Applications V, 2018 If a scanning illumination spot is combined with a detector array, we acquire a 4 dimensional signal. Unlike confocal microscopy with a small pinhole, we detect all the light from the object, which is particularly important for fluorescence microscopy, when the signal is weak.

Advanced Photonics Research, Volume 7, Issue 6, June 2026.A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...
