“…In general, multiple exposures must be adopted for recording the hologram, which is not suitable for real-time imaging or dynamic monitoring. In addition, for conventional phase shifters, [17][18][19][20] mechanical operation will inevitably result in vibration, which may affect the accuracy of phase shift and degrade the image quality.…”

A method of single-shot phase-shifting digital holography with a photon-sieve-filtering telescope is proposed. Three copy images with different phases are first generated by use of a monofocal photon-sieve filter in Kepler telescope, and then interfere with the reference plane wave by a beam combiner. The hologram is captured by a charge-coupled device (CCD) in one single exposure. The complex-valued amplitude of the test object can be reconstructed by three-step phase-shifting interferometry through three frames of extracted sub-interferograms from the single-exposure hologram. The principle and simulation experiments are carried out and verified the validity of our proposed method. This method can be applied for snapshot imaging and three-dimensional object construction.

“…PS-FBG has been successfully applied in single longitudinal mode (SLM) fiber ring laser (FRL) [15,17]. In this paper, the PZT is used to induce phase shift (PS) in CFBG, and the PZT-based PS-CFBG has been successfully applied in SLM FRL [17,18]. For further study, the PZT-based PS-CFBG has been theoretical and experimental analyzed in our previous work [19].…”

In this letter, a Q-switched erbium-doped fiber ring laser (EDFRL) with piezoelectric transducer (PZT)-based phase shift chirped fiber Bragg grating (PS-CFBG) has been proposed and demonstrated first. As known, the phase shift can be induced and wiped periodically by applying a modulation signal on the PZT. This makes it possible for the PZT-based PS-CFBG to be used in Q-switched EDFRL. To verify the performance of this Q-switched EDFRL system, some theoretical analyses and experiments have been performed. It is found that, when the PZT is modulated by a signal with frequencies of 1 and 2 kHz, pulse widths of the Q-switched pulse train are 19.8 μs and 15.6 μs, respectively. Besides, the corresponding pulse energies are 1.16 μJ (1 kHz) and 1.91 μJ (2 kHz) with a pump power of 90 mW.
