摘要
The present invention relates to a common-path interferometric scattering imaging system and a method of using such a system, where the system includes an illuminating unit for emitting an illumination beam; a light collecting arrangement for collecting through a common collection optical path a scattered beam provided by the light scattering on an object of the illumination beam and a reference beam provided by the reflection on or transmission through an interface of the illumination beam; an image sensor (D) for receiving and sensing the collected scattered and reference beams interfering thereon as an interferometric light signal; an attenuation mechanism arranged in the common collection optical path for attenuating the reference beam before it arrives at the image sensor; and a processor to process data corresponding to the interferometric light signal.
