Fourier single-pixel imaging is one of the main single-pixel imaging techniques. To improve the imaging efficiency, some of the recent method typically select the low-frequency and discard the high-frequency information to reduce the number of acquired samples. However, sampling only a small amount of low-frequency components will lead to the loss of object details and will reduce the imaging resolution. At the same time, the ringing effect of the restored image due to frequency truncation is si...

We report the fabrication and optical characterization of thin diamond membranes implanted with negatively charged silicon vacancy (SiV−) centers. The variations in the membrane thickness enable the experimental study of optical coherence of SiV− centers as the membrane thickness is varied from 100 nm to 1100 nm. Photoluminescence excitation spectroscopy at low temperature shows that most of the SiV− centers in these membranes feature an optical linewidth ranging between 200 and 300 MHz. Further...
