  • Tunable dispersive optical system
    Patent number: 7317575
    Abstract: A novel dispersion optical system based on at least one grating is provided. The pitches of the grating are linearly modulated so that the incident light is dispersed into different monochromatic light at different diffraction angles. In such a system, an order sorting filter is not required to separate the light of a selected order from the rest of unwanted overlapped order.

  • Method for measuring magnetic field based on electro-optic probing technique and measuring electric field based on magnetic probing technique
    Patent number: 6674281
    Abstract: The present invention provides a method for measuring both magnetic and electric fields of a DUT via an electro-optic probing technique at the same time. Also, the present invention provides a method for measuring both electric and magnetic fields via a magneto-optic probing technique simultaneously. The method utilizes the modulation of the position of a probe to measure the electric and magnetic field signals. The DC and AC components of the modulated electric (or magnetic) field signals can be obtained by means of a low pass filter and a lock-in amplifier, respectively. Through a simple calculation, the electric and magnetic field can be obtained simultaneously.
