A method of monitoring an elevator car is provided. The method comprising: moving the elevator car through a route segment in a first direction; moving a sensing system integrally connected to the elevator car over a segment of a scattering surface, the sensing system comprising a first light source and a first light sensing device; emitting a plurality of first light impulses onto the scattering surface using the first light source at a first impulse rate; measuring a first data set comprising light scattered off the scattering surface for each of the first light impulses using the first light sensing device; and determining a first velocity of the elevator car in response to the first data set and a baseline data set.
