Currently
the IR cameras are broadly used in the optic-electronic tracking
optic-electronic measuring
fire control and optic-electronic countermeasure field
but the output sequence of the most presently applied IR cameras in the project is complex and the giving sequence documents from the leave factory are not detailed. Aiming at the requirement that the continuous image transmission and image procession system need the detailed sequence of the IR cameras
the sequence measurement system of the IR camera is designed
and the detailed sequence measurement way of the applied IR camera is carried out. The FPGA programming combined with the SignalTap online observation way has been applied in the sequence measurement system
and the precise sequence of the IR camera's output signal has been achieved
the detailed document of the IR camera has been supplied to the continuous image transmission system
image processing system and etc. The sequence measurement system of the IR camera includes CameraLink input interface part
LVDS input interface part
FPGA part
CameraLink output interface part and etc
thereinto the FPGA part is the key composed part in the sequence measurement system. Both the video signal of the CmaeraLink style and the video signal of LVDS style can be accepted by the sequence measurement system
and because the image processing card and image memory card always use the CameraLink interface as its input interface style
the output signal style of the sequence measurement system has been designed into CameraLink interface. The sequence measurement system does the IR camera's sequence measurement work and meanwhile does the interface transmission work to some cameras. Inside the FPGA of the sequence measurement system
the sequence measurement program
the pixel clock modification
the SignalTap file configuration and the SignalTap online observation has been integrated to realize the precise measurement to the IR camera. Te sequence measurement program written by the verilog language combining the SignalTap tool on line observation can count the line numbers in one frame
pixel numbers in one line and meanwhile account the line offset and row offset of the image. Aiming at the complex sequence of the IR camera's output signal
the sequence measurement system of the IR camera accurately measures the sequence of the project applied camera
supplies the detailed sequence document to the continuous system such as image processing system and image transmission system and gives out the concrete parameters of the fval

pixclk
line offset and row offset. The experiment shows that the sequence measurement system of the IR camera can get the precise sequence measurement result and works stably

One of the effective method of improving diamond tool life on rulling large diffraction gratings is developing precise double-cone edged on line edge transfering tool. But traditional died weight or manual lapping technique couldn't meet the precision requirement of on line edge transfering tool. So preliminary studied rigid lapping of diamond grating ruling tool. Choosing traditional BC6063 shaping machine and made a series of alteration on it
achieved the automation of lapping process of diamond grating ruling tool. Through lapping grating ruling tool and AFM measurement find that the surface roughness of tool is 1.51nm
the radius of tool edge is 160nm
edge quality is good enough
this verified the feasibility of rigid lapping of diamond grating ruling tool and lay the foundation for developing precision lapping machine. (2011) Trans Tech Publications

Image segmentation is primary issue in image processing
at the same time it is principal problem in low level vision in computer vision field. It is the key technology to process image analysis
image comprehend and image depict successfully. Aim at measurement of granularity size of nonmetal grain
a new algorithm of image segmentation and parameters calculation for overlapping grain image is studied. The hypostasis of this algorithm is present some new attributes of graph sequence from discrete attribute of graph
consequently achieve that pick up the geometrical characteristics from input graph
and new graph sequence which in favor of image segmentation is recombined. The conception that image edge denoted with "twin-point" is put forward
base on geometrical characters of point
image edge is transformed into serial edge
and on recombined serial image edge
based on direction vector definition of line and some additional restricted conditions
the segmentation twin-points are searched with
thus image segmentation is accomplished. Serial image edge is transformed into twin-point pattern
to realize calculation of area and granularity size of nonmetal grain. The inkling and uncertainty on selection of structure element which base on mathematical morphology are avoided in this algorithm
and image segmentation and parameters calculation are realized without changing grain's self statistical characters.
