    摘要: The present invention relates to a scanning microscope using an I/Q-interferometer. The scanning microscope includes an I/Q-interferometer which demodulates the phase change and amplitude change induced on the probe beam to provide the I- and Q-signals, an XY scanner, a scanner driver, a precision motion stage controlling the displacement of the sample along the direction parallel to the direction of the probe beam, a motion stage driver, a focusing/collimating device, and a computer. The computer transfers control commands to the scanner driver for scanning the XY scanner, receives I- and Q-signal provided from the I/Q-interferometer, processes the I- and Q-signal to obtain the corresponding phase and amplitude values at each scanning point, calculates error signal for maintaining constant phase during the scanning, and transfers commands to the motion stage driver for the precision motion stage to compensate for phase changes caused by surface morphology during the scanning.The scanning microscope performs a multilayer scanning or a constant phase scanning to extract information for the surface or inside of the sample.

    摘要: An optical wireless communications network connects a plurality of communication cells, which are defined by dividing a local communication area, for enabling optical wireless communication in each of the communication cells. An optical signal transmitter is installed in each communication cell for irradiating the cell with a data-modulated optical signal to perform data transmission to a terminal located therein. The optical signal transmitter comprises an optical signal source for outputting the data-modulated optical signal, and an optical signal diffuser with a concave inside surface facing the output end of the optical signal source for diffusing and reflecting the data-modulated optical signal to irradiate the cell.
