Noise-tolerant single photon sensitive three-dimensional imager

Abstract: Active imagers capable of reconstructing 3-dimensional (3D) scenes in the presence of strong background noise are highly desirable for many sensing and imaging applications. A key to this capability is the time-resolving photon detection that distinguishes true signal photons from the noise. To this end, quantum parametric mode sorting (QPMS) can achieve signal to noise exceeding by far what is possible with typical linear optics filters, with outstanding performance in isolating temporally and spectrally over… Show more

“…Half waveplates on both arm, before the nonlinear crystal, are used to ensure the vertically polarized optical field parallel to the crystal's optical axis. The output pulses are then filtered with a short-pass filter to remove any residual fundamental light and bandpass filters to provide a total >180 dB extinction in rejecting the second harmonic of the pump [43,46]. The visible SF photons pass through a half waveplate and polarizing beam splitter.…”

“…Single-photon imaging can detect low-intensity light, showing weak optical signals with single photon sensitivity (Rehain et al, 2020;He et al, 2022). Mostakim and partners reported Hf-based UiO-66 MOFs with high hydrolytic stability and catalytic activity (Sk et al, 2018).…”

“…[14][15][16][17][18][19] For example, in time-of-flight imaging DOI: 10.1002/lpor.202100635 systems, the histogram of photon arrival times compared to a pulsed illumination laser reference determines the spatial depth resolution of the target. [1][2][3][4][5][6][7][8] In fluorescence lifetime techniques, the distribution of time-delays between an excitation laser pulse and the emitted fluorescence photons allows for the spectroscopic identification of molecules of interest [11,13] as well as contrast between different tissue structures when applied to microscopy. [12,13] In quantum processing, the ability to measure small time differences of single photons from a reference pump laser influences how densely information can be encoded and detected on a quantum communication channel.…”
