An imaging system according to the present invention includes: a light source unit which emits illuminating light to illuminate an object; an illuminating-light transmitting unit which transmits the illuminating light; a timing adjustment unit which, being placed between the illuminating-light transmitting unit and the object, varies timing with which rays contained in the illuminating light which has passed through the illuminating-light transmitting unit reach a surface of the object; a reflected-light incidence unit upon which reflected light coming from the surface of the object is incident; a light detection unit which temporally breaks down the reflected light incident upon the reflected-light incidence unit, converts the reflected light into an electrical signal, and outputs the electrical signal in sequence; and a signal processing unit which converts the electrical signal outputted in sequence by the light detection unit into pixel information about an optical image on the surface of the object.
