WebPhase-inserted fiber gratings (PI-FGs) refer to those gratings where there exist a number of the phase-shifts (spatial spacing) among different sections (or local periods) of the gratings themselves. All the PI-FGs developed to date can mainly be divided into three categories: phase-shifted gratings, phase-only sampled gratings, and phase-modulated gratings, of … Websampling (ASOPS) [18-21], dual-comb spectroscopy [22-24], and dynamic optical sampling by laser cavity tuning (OSCAT) [25-30] . They have demonstrated the feasibility or potential to reach a measurement updating rate well above 1 kHz, and in some cases, into the megahertz range [24]. Here, we propose a new scheme, which combines key aspects of

The chief goal of OSCAT is to alleviate the need for two femtosecond lasers while retaining the ability to make deep and rapid scan of the relative pulse delay. This is accomplished by combining laser intra-cavity modulation with an arm-length mismatched interferometer [25, 30].
