本文以我院研制的GXS—1、GXS—2型高速狭缝摄影机为基础,参照国内外有关资料论述了狭缝成象原理及电控技术。全文分两部分。第一部分介绍狭缝相机的类型、基本结构、狭缝成象的原理。第二部分着重探讨时标驱动、行程控制、磁测速等电控技术问题。第一部分一概述高速狭缝相机又称弹道同步摄影机是外弹道测试的重要工具。用狭缝相机能得到弹丸飞行的大幅清晰照片、从照片可以仔细观察弹丸的表面状况,部件分离和飞行中产生的故障。能根据已定的标准确定弹的飞行姿态。(见照片一、二) 如果沿着弹丸飞行方向建立一系列摄影站。每站的两台狭缝相机互相正交,并由时统装置发出的有序脉冲统一操作。那么,根据储存在时统装置中的各站触发时刻和记录 Based on the GXS-1 and GXS-2 high-speed slit cameras developed by our institute, this paper discusses the slit imaging principle and the electronic control technology with reference to relevant data at home and abroad. The full text is divided into two parts. The first part introduces the type of slit camera, the basic structure, the principle of slit imaging. The second part focuses on time-driven, travel control, magnetic speed and other electronic control technology issues. The first part of an overview of high-speed slit camera, also known as ballistic synchronous camera is an important tool for ballistic testing. A sharp, sharp picture of the projectile’s flight can be obtained with a slit camera and the surface condition of the projectile, part separation and flight faults can be carefully observed from the photographs. According to the established standards to determine the bomb flight attitude. (See photos one and two) If a series of photography stations are set up along the direction of the projectile flight. The two slit cameras at each station are orthogonal to each other and are operated by the ordered pulse emitted by the system. Then, the moment and record are triggered based on the stations stored in the device
