A shadow shooting system and method capable of realizing ultra-high speed, high resolution and large field of view

Abstract

The invention relates to a shadow method shooting system and method capable of achieving a superspeed ultrahigh resolution large visual field. The shooting system comprises a pulse laser, a reflector,an acrylic fluorescent screen, a convex lens, an oil injector, a 550nm high pass filter and an industrial cam which are successively arranged along a pulse laser path, a laser control cabinet connected to the pulse laser, a manual relay switch connected to the laser control cabinet, and a digital delayed pulse generator separately connected to the oil injector, the industrial camera and the manual relay switch. The system and method can achieve superhigh speed shooting through a high performance CCD camera or industrial camera to obtain high resolution pictures which are relatively large in visual field, so that the limit on the high speed camera is overcome.

Description

Technical field: [0001] The invention relates to an ultra-high-speed, high-resolution and large-field-of-view shadow shooting system and method. Background technique: [0002] With the rapid growth of my country's economy, the total number of automobiles has also increased sharply. While cars bring convenience to people, they also bring a series of environmental pollution problems. The environmental pollution problems that appeared in the process of industrialization in developed countries have correspondingly appeared continuously in my country in the past 20 to 30 years. Therefore, the development of high-efficiency and low-emission internal combustion engine combustion systems has become the focus of research. [0003] In recent years, with the continuous improvement of the size of the direct injection gasoline engine and the continuous improvement of the fuel injection pressure, the problems of fuel impingement on the wall and the resulting soot emission, oil dilution ...

AI Technical Summary

Problems solved by technology

If traditional continuous strong light sources such as xenon lamps, halogen lamps, etc. are used for lighting, if the shooting speed of the camera is lower than the moving speed of the object, a "drawing" blur phenomenon will occur, that is, part of the moving track of the object will be recorded and the actual object will be distorted. Phenomenon

At present, the shooting speed of commonly used high-speed cameras can reach up to 500,000fps, that is, 500,000 pictures per second, but limited by the high-speed camera system and its memory, the faster the shooting speed, the smaller the shooting field of view, and the light source required to illuminate the picture The stronger the light intensity, the blurry and darker the pictures taken during high-speed shooting and the shooting area is extremely small
