Problems solved by technology

[0005] The dot frequency of the above two dotting timers is 50Hz, which cannot be adjusted. The dot spacing is too large when describing the fast movement state, causing serious waste of paper tape, and the dot spacing is too small to accurately measure when describing the slow movement state.

Abstract

The invention discloses a frequency conversion laser motion recorder. The frequency conversion laser motion recorder comprises a pulse laser capable of frequency modulation, a photosensitive paper tape, a horizontal-U-shaped support frame and a fixation apparatus. According to different moving speeds of a detected moving object, the pulse emission period of the pulse laser can be adjusted to a proper size so that data acquisition and analysis are facilitated. The fixation apparatus fixes the horizontal-U-shaped support frame on a desktop or an experiment table surface such that unnecessary experiment errors caused by movement in an experiment are avoided.

Description

technical field [0001] The invention relates to the technical field of physical experiment instruments, in particular to a frequency conversion laser motion recorder. Background technique [0002] In middle school physics experiments, the dot timer is the most widely used. The dot timers currently used mainly include electromagnetic dot timers and electric spark dot timers. [0003] The common point of these two timers is to record the "time-space" distribution information of moving objects on the paper tape. The timing reference is taken from the cycle of household electricity. s, so it has the same data collection method and data collation and analysis method, and can be used with inclined trolleys and rail trolleys. [0004] At the same time, these two kinds of timers also have obvious defects in the process of actual experimental operation. When the electromagnetic dotting timer is working, the periodic change of the magnetic field is caused by the mains electricity th...
