High factor, fails to be widely used.
What above-mentioned all kinds of imaging devices were adopted is nearly all face formation CCD, is realized by multiple spot or multi-angle imaging
Observation in panoramic range.Although acquisition and observation of face formation CCD to image meet human eye direct feel, because of production technology
Restriction, often row pixel number is generally fewer than linear array type many for face formation CCD, the area of single area array CCD, pixel number and limited
The frame amplitude-frequency of system is all difficult to meet the demand under specified conditions to big field detection.On the other hand, area array CCD need to be by being spaced rotation
Turn certain angle to obtain the panoramic picture of a part, when real-time, high frequency imaging is gathered, larger data volume is to storing and passing
Defeated speed all has higher requirements.Line array CCD has more flexible pixel dimension, bigger one-dimensional pixel number, higher frame amplitude-frequency
The advantages of so that the image resolution ratio after splicing fusion is greatly improved, and can meet the observation requirement of all kinds of large visual field environments.
