Abstract: Detecting a multi-path interference component in a time-of-flight (ToF) camera may be performed by generating a confidence map in which a distortion area attributable to a multi-path interference component included in a reflection modulation signals is specified, where the reflection modulation signals is generated when two modulation signals emitted from a light source to a subject return to the ToF camera after being reflected by the subject. Correcting the multi-path interference component corrects distortion attributable to a multi-path interference component, which may include correcting only the distortion area specified in the confidence map. Detecting the multi-path interference component in a ToF camera includes collecting the reflection modulation signal at a plurality of different times, calculating amplitudes and offsets of the collected reflection modulation signals, determining whether a multi-path interference component is included in the reflection modulation signal, and generating the confidence map.

Abstract: An apparatus for inspecting a display panel for defects includes a table which supports the display panel, a laser excitation unit that irradiates a non-display area of the display panel with a point laser beam, a thermal wave detecting unit that generates thermal wave images of irradiated portions of the non-display area, a driving unit, and a control unit. A groove corresponding to an edge of the display panel may be defined in a top surface of the table. A defect, such as a crack, may be detected by comparing a defect pattern obtained from the thermal wave images with a pre-registered defect pattern.
