A new phase measurement method is designed and presented by using the technique of signal shifting phase and the technique of signal multiplication for laser rangefinder. The intensity of laser light is modulated by cosine circuit signal
at the same time the cosine circuit signal is thansformed sine signal by the shifting phase technique. Two signals mentioned above are multiplied by received signal from the target respectively
then being transmitted into signal processor after passing through low band filter respectively. The result of phase-shift between the received signal and sent signal is calculated by means of signal processor and time-counter with double frequency of modulation signal. The proposed system is composed of four units such as control and count unit
emitting and receiving unit of laser light
signal processing unit and result display unit. The two most advantages of proposed system over others are its ability of proper isolation which reduces crosstalk and its independency thermal drift. Theoretical calculations and experimental results have shown the accuracy better than 2 mm. 2010 Copyright SPIE - The International Society for Optical Engineering.

With the coming of the high-speed digital system age
signal integrity (SI) and electromagnetic compatibility (EMC) should not be ignored any more. In this paper
based on basic theories of SI and EMC
the high-speed digital design method for PCB using the SI simulation tool of Altium Designer 6 and EMC analyses is introduced
and the impedance control
power integrity (PI) design and SI (reflections and crosstalk) design of a piece of image processor PCB are demonstrated in detail. The simulation results show that the impedance control is perfect
reasonable termination can improve the waveforms and control the reflections and crosstalk. 2009 IEEE.

A 32 32 arrayed waveguide grating (AWG) multiplexer operating around the 1550 nm wavelength has been designed and fabricated using fluorinated poly (ether ether ketone). The schematic layout is about 3.21.7 cm 2. For our AWG
the total loss of designed AWG multiplexer is calculated to be 4.5 dB. We fabricated the AWG multiplexer by spin coating
photolithographic patterning and reactive ion etching (RIE). The core size is 55 m2. The roughness of polymer surface was reduced by 20 nm using a remelting technique. The measured wavelength channel spacing of the fabricated AWG multiplexer is 0.796 nm and center wavelength is 1548 nm. The inserting loss of the AWG is 9.5 dB and crosstalk less than -20 dB.

Optical switch is one of key supporting technologies in all-optical-network (AON). And electrostatic MOEMS (Micro-Optical-Electro-Mechanical Systems) switch plays a very important role in all the researched switches
because of their excellent features
including low insertion
low crosstalk and scalability. But the packaging technology has been limiting the development of optical switch. In this paper
the authors study the laser beam propagating during the free space and select collimator
design the pedestal to packaging and address aspects of the insertion loss that are most important loss mechanisms for the 2D cross-connect switch.

It is important to study the interaction effect between laser and photoelectric detector. In most of the laser detecting systems
laser must irradiate the photoelectric detector. The detector will be saturated or damaged easily if the fluence of the laser is higher than the saturation threshold of the detector. Now
many photoelectric detectors are used in space. To achieve their interaction
"Cat's eye" effect is applied to find and locate the remote aerial detector by laser. The possibility and mechanism of disturbance to remote aerial detector induced by laser are analyzed
and the factors of influence are also analyzed. The fluence of laser on the photoactive area of remote aerial detector is estimated. With two samples of CCD and TV tracking system
the mechanism of soft damage to CCD and TV tracking system induced by laser are introduced. The saturation of CCD and crosstalk of CCD are the main reasons of disturbance. When the tracking system is used in wave-door tracking mode
it will lose its tracking target if the saturation or crosstalk of CCD can enter into wave-door. At last
the influence to disturbance induced by atmosphere effect is also analyzed.
