The streak tube imaging lidar (STIL) system is a new 3D imaging technology that can obtain a complete frame image of the target with only one laser pulse and it has many advantages such as high frame rate, big field of view and so on over the scanning-mechanism system. The principle of the experiment will be introduced firstly and the pre-process of the data will be simply discussed, such as correction of image distortion, the noise filter and image enhancement, data segmentation and so on. All the methods to the above data pre-process are specially adopted for the STIL system. The range of the target, the time of the photoelectron flight and the range of the target image on the phosphor screen have a linear relationship and it will be proved; according this, a mathematical model to reconstruct the 3D image is put forward and the algorithm to calculate the relative range of the target is confirmed. Based on the model and the algorithm, a program in the VC++ and matlab environment to analyze the lidar data, reconstruct and display the 3D image of the target is compiled. The result verifies the model and the algorithm effective.

Projection Angle

Three-dimensional (3D) microstructure visualization on the electron microscope requires that the sample be tilted to different positions to collect a series of projections. This tilting should be performed rapidly for on-line stereo viewing and precisely for off-line tomographic reconstruction. Usually a projection series is collected using mechanical stage tilt alone. The stereo pairs must be viewed off-line and the 60 to 120 tomographic projections must be aligned with fiduciary markers or digital correlation methods. The delay in viewing stereo pairs and the alignment problems in tomographic reconstruction could be eliminated or improved by tilting the beam if such tilt could be accomplished without image translation.A microscope capable of beam tilt with simultaneous image shift to eliminate tilt-induced translation has been investigated for 3D imaging of thick (1 μm) biologic specimens. By tilting the beam above and through the specimen and bringing it back below the specimen, a brightfield image with a projection angle corresponding to the beam tilt angle can be recorded (Fig. 1a).

Abstract Next generation assembly/package development challenges are primarily increased interconnect complexity and density with ever shorter development time. The results of this trend present some distinct challenges for the analytical tools/techniques to support this technical roadmap. The key challenge in the analytical tools/techniques is the development of non-destructive imaging for improved time to information. This paper will present the key drivers for the non-destructive imaging, results of literature search and evaluation of key analytical techniques currently available. Based on these studies requirements of a 3D imaging capability will be discussed. Critical breakthroughs required for development of such a capability are also summarized.
