Abstract

本实用新型是为记录、演示、分析物体运动轨迹而设计的物体运动轨迹摄制仪,以满足物理教学实验的需要。该摄制仪由底座前端带调速驱动电机的调速转盘和位于测速转盘后面、镜头正对测速转盘曝光孔的数码照像机组成,该仪器采用遮挡法用数码像机进行连续拍摄,通过计算机辅助,可及时显示、打印结果,供分析处理。其直观性好,精确度高,适应面广。

Description

物体运动轨迹摄制仪
本实用新型涉及物理实验及教学用具,即物体运动轨迹摄制仪。
在物理实验或物理教学中,为了记录和描述物体运动的轨迹,如自由落体、平抛、斜抛、碰撞等,需要将其轨迹记录下来,现有的方法是采用频闪照像法,用感光胶片记录下离散的轨迹点,待底片冲洗后再用逐差法处理离散轨迹点间的数据,以求得物体的加速度和损失速度等参数。该方法形象直观,而且准确度较高,但拍摄过程只限于在暗室中进行,而且受频闪光源功率的限制,拍摄区域不大。加之照片冲洗麻烦,更不便观看辨认和进行数据处理,影响教学演示效果。
本实用新型的目的就是要设计一种物体运动轨迹摄制仪,方便、快速的采集、记载物体的运动轨迹,以适应科研和教学实验要求。
为完成发明目的而设计的物体运动轨迹摄制仪由底座前端带调速驱动电机的测速转盘和位于测速转盘后面正对测速转盘的曝光孔的数码照像机组成,底座下有可调支架。
本实用新型物体运动轨迹摄制仪由于采用了数码照像技术,用遮挡法代替频闪法进行连续拍摄,并通过计算机辅助,可及时以大屏幕显示或打印实验过程及结果。摄制过程不必在暗室中进行,且不受照明光源及拍摄区域的限制。实验结果清晰、数据处理分析方便。
以下结合附图实施例描述本实用新型。
图1为本实用新型实施例物体运动轨迹摄制仪示意图。
如图1所示,本实用新型物体运动轨迹摄制仪由底座4前端带调速驱动电机6的测速转盘7后面镜头2正对测速转盘7的曝光孔1的数码照像机3组成,底座4下有可调支架5。
