Abstract: A range-gated shearography system and related methods. Implementations of range-gated shearography systems may include a laser light source, at least one imaging detector coupled to the laser light source, a shearing interferometer coupled to the at least one imaging detector, and a ranging detector coupled to the laser light source. A method of range-gating a shearography system may include emitting laser light, determining a range interval for at least one object, receiving reflected laser light from the at least one object through a shearing interferometer from the range interval, and collecting at least one shearography image.
