Abstract |
A procedure is described for measuring the velocity of blood spatter generated by a Medium Velocity Impact (1.5-7.5 m/sec.). The blood spatter was created by allowing a steel cylinder to fall free through a hollow pipe into a pool of blood. As the cylinder exited the lower end of the pipe it passed through an infrared beam which triggered two strobe lights set to fire at preselected intervals. As the blood left the impact site, a camera recorded a double image from the two strobes. A 15 cm rule included in the photographs provided a scale for measuring the distance between images. |
