Propose a new measurement system of autocollimation form laser grating heterodyne interferometer. Take grating diffraction and polarization optics as theoretical foundation
second
furthermore
combined with electronics knowledge to analyze the system. First
make use of autocollimation diffraction of grating
measurement information obtained by dual-frequency laser belongs to ac signal
the interferometer measurement system take grating pitch as measuring datum
the structure is simple
possess great gain and high signal-noise ratio
therefore
stable
completely overcome the disadvantages of DC level drift caused by light intensity variation of single-frequency laser
system can achieve nanometer resolution. 2010 IEEE.
reduce the impact of environmental factors
easy to install and debug
measurement error is small

A new transceiving protocol is demonstrated for a Free Space Optical (FSO) communication system
and it's discussed in two parts: the transmitting protocol and the receiving protocol. During the discussion of these two parts
the cooperation of them is also discussed. Different from wired communication
an FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere
and the protocol presented in this paper is mainly optimized for terrestrial Free Space Optical links
in which the signal channel of the system is mainly the atmosphere. Due to the complex composition and activity of the atmosphere
this signal channel brings in great influence on the transmitting laser in it
for example
the absorption and scattering of the atmosphere molecules and aerosols
the scintillation of received laser power caused by the turbulence of the atmosphere
all of which results in a much higher Bit Error Rate (BER) of the communication system. Thus in designing a protocol for an FSO system
more effort should be taken in the encoding of the data stream
the synchronization of the data stream
error checking and exception handling. The main function of the transmitting protocol includes interfacing the outer input data with a parallel port
buffering the input data
encoding the input data stream
serializing the parallel data and output the serialized data. It also has an output management unit to manage the activity of each part of the transmitting protocol. The main function of the receiving protocol includes filtering and synchronizing the input serial data stream
paralleling the serial data stream
decoding the input data
error checking
exception handling and interfacing the outer receiver with a parallel port. The entire transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. The presented protocol could be taken as "protocol transparent" for outer interfaces
meaning that when interfacing the presented system to an outer system
you don't have to consider what protocol the outer system transceiving data stream is under
for example
the TCP/IP protocol or anything else
in the case that its I/O interface is a parallel port. Simulation and final experiment prove that the protocol presented is working fine at a certain bit rate scale. 2009 SPIE.
