1. A detector for detecting a condition of a rail vehicle undercarriage component comprising:
- a sensor having infrared sensing elements, each of the elements configured to scan regions of a target area of the rail vehicle undercarriage component, the sensor being oriented so that at least one of the elements receives unobstructed infrared emissions from the rail vehicle undercarriage component,wherein the sensing elements are arranged in a matrix of a plurality of arrays, and wherein a first array of first sensing elements includes the first sensing elements arranged in a first straight line to scan a first portion of the rail vehicle undercarriage component along a perimetric segment of the rail vehicle undercarriage component, and a second array of second sensing elements includes the second sensing elements arranged in a second straight line that is parallel to the first straight line to scan a second portion of the rail vehicle undercarriage component that is at a different point along the perimetric segment of the rail vehicle undercarriage component to provide redundancy in the detection of the condition.
