Abstract:
Disclosed herein is a method for measuring the vibration of a mirror in a vehicle. The method includes attaching a source of electromagnetic radiation to the vehicle, attaching a detector of electromagnetic radiation to the vehicle, positioning the source so that radiation emitted thereby strikes the mirror and reflects therefrom to strike the detector, driving the vehicle while emitting radiation from the source, recording the positions on the detector where the radiation strikes, and determining a vibration index based on the spatial distribution of the positions on the detector where the radiation strikes.
