Speckle detection systems, image capturing devices and methods

A vehicle speckles detection system for detecting one or more speckles on an exterior surface of an optical element of an image capturing device of a vehicle, the system comprising:

• one or more light sources configured to emit a light towards the optical element, the optical element being configured to reflect the light from the light sources when speckles are located on the exterior surface of the optical element that directly contacts an external environment to the vehicle,
• one or more light receivers receiving, when the vehicle is being driven, the light reflected by the optical element such that speckles on the exterior surface of the optical element are detected;
• and
• a housing positioned on the vehicle and extending longitudinally from a first end to a second end, the housing having a coupling surface that defines an inner space;
• wherein the one or more light receivers comprise a broadband detector detecting, when the vehicle is being driven, the light by at least one of under 400 nm and over 780 nm and preventing the emitted light from interfering with an image captured by the image capturing device.
