We investigate the Airy-Talbot effect of an Airy pulse train in time-dependent linear potentials.The parabolic trajectory of self-imaging depends on both the dispersion sign and the linear potential gradient.By imposing linear phase modulations on the pulse train,the Airy-Talbot effects accompanied with positive and negative refractions are realized.For an input composed of stationary Airy pulses,the self-imaging follows straight lines,and the Airy-Talbot distance can be engineered by varying the linear potential gradient.The effect is also achieved in symmetric linear potentials.The study provides oppor-tunities to control the self-imaging of aperiodic optical fields in time dimension.

At the mirrors of a laser diode self-mixing interferometer,the output beams carry anti-correlated[i.e.,in phase opposition]interferometric signals,whereas the superposed noise fluctuations are[partially]correlated.Therefore,by using an instru-mental outpu
