TL;DR: Lens parameters of CCD camera, such as focal length, camera format, F stop, depth of field, angle of view, C or CS mount and so on, were described and the main processes for selecting C CD camera lens in reason were introduced.
Abstract: Lens parameters of CCD camera, such as focal length, camera format, F stop, depth of field, angle of view, C or CS mount and so on, were described. The relationships of the parameters, also the brief introduction of CCD camera were discussed. The reference information for selecting the various lenses was presented. Lastly, the main processes for selecting CCD camera lens in reason were introduced.

TL;DR: The return loss for C-lens collimators was calculated by using the methods of the geometry optics and the matrix optics and those factors determined by the quality of C-analyses wore were also analyzied.
Abstract: The return loss for C-lens collimators was calculated by using the methods of the geometry optics and the matrix optics. Those factors determined by the quality of C-lens collimators wore also analyzied. These results of calculation and analysis may be to direct the optimizing design of C-lens collimators.

TL;DR: A photoelectric detection device made for detecting the tracks of motorcycles whose drivers want to pass the driving exam was instructed, one of anti-jamming measures that raise both the ability of signal and the reliable operation of system.
Abstract: A photoelectric detection device made for detecting the tracks of motorcycles whose drivers want to pass the driving exam was instructed. The system's components and work principle were described in detail. The visible laser beams of red wavelength act as borders and the Hall proximity switches do the barriers in this system which has a kernel of AT89C52. The device surveys whether the motorcycle oversteps the boundary or collides the obstacle .The single chip of the system communicates with PC in mode of two-way serial communication so that the program starts and ends under the control of PC mean well checkout data and examination results delivered to PC. The method is one of anti-jamming measures that raise both the ability of signal and the reliable operation of system.
