The optical sampling technique is a novel method to perform time-resolved measurements of optical data signals at high bit rates with a bandwidth that cannot be reached by conventional photodetectors and oscilloscopes.

A continuous laser sampling ICP AES system with simple structure and good stability for the direct analysis of solid samples is introduced in this paper.

Circuit design of luminosity sampling for the spectrophotometer;

Microwave from 1￣5GHz was measured by the CPW electro optic sampling with multiple frequency phase shift scanning system.

An external electro optic sampling system using a LiTaO 3 tip with a gain switched DFB laser diode was described.

The electro optic sampling system constructed with the multiple frequency phase shift scanning method was introduced.

We propose a novel all-optical sampling method using nonlinear polarization rotation in a semiconductor optical amplifier.

The all-optical sampling based on the nonlinear polarization rotation in semiconductor optical amplifiers has the advantages of high-speed operation and small pump power,and it shows a possible solution for high-speed all- optical analog-to-digital (A/D) conversion.
