Abstract:
1. An inspecting device which takes a semiconductor device or a photo device as an inspecting target, the device comprising: a light source for emitting pulsed light; a scan part for obliquely irradiating an inspecting target with said pulsed light, while changing an optical path of said pulsed light, to scan said inspecting target with said pulsed light; a detection part for detecting an electromagnetic wave emitted non-coaxially with said pulsed light from said inspecting target in accordance with the illumination with said pulsed light; and an image generation part for generating an image indicating electric field intensity distribution of said inspecting target based on an electric field intensity of an electromagnetic wave detected by said detection part, wherein said image generation part decides a position on said image which corresponds to an acquisition point of an electromagnetic wave intensity based on an incidence angle of said pulsed light on said inspecting target.
