DEVICE FOR MEASUREMENT OF SPEED AND ACCELERATION OF THROWN OBJECT

摘要

FIELD: inspection-measuring technique. ^ SUBSTANCE: device has frames disposed at ends of measure route. Mirrors are installed at sides of any frame. Frames have to be detectors of passage of thrown object. Frames have vertical and lower horizontal walls. Frames are disposed along trajectory of passage of thrown object. There are semiconductor laser radiators fastened to vertical walls of frames. Radiators form mesh composed of laser beams. Passage detector is mounted onto cut of shaft of throwing device and it is connected with controlled quartz pulse oscillator. Other passage detectors are placed at base distances. Detectors are connected with pulse counters. Pulse counters are connected with controlled quartz laser oscillator. Passage detector, mounted at cut of shaft of throwing device, starts controlled quartz pulse oscillator. ^ EFFECT: simplified design; improved reliability; widened operational abilities. ^ 2 dwg
