In this paper  a plane arranging method of fiber-optic array based on Si-V grooves is established in order to improve the accuracy and reduce the cost of manufacturing. Firstly  the Si-V groove array is micro-machined with anisotropic etching process  then optical fibers are placed in the grooves orderly with plane arranging method. Secondly  the end surfaces of the device are polished  also the linear fiber-optic image slicer is packaged. Finally  some parameters are tested  including structure parameters  transmittivity and vibration test. Experimental results indicate that the maximum error accumulated in 2000 periods of the Si-V grooves is 0.5 m  the error of the height in Si-V grooves is less than 0.15m  the roughness of the end surface is less than 0.9nm. The transmittivity of the linear fiber-optic image slicer that without optical film is 51.46% at the wavelength of 632.8nm. After random vibration experiment  the ratio of the broken fiber increased by 0.1%. While the temperature reached 320C  the stress of epoxy will be 130Mpa  which is close to the limit resistance stress of 139Mpa  some cracks appeared.
