The path detection system is arranged at a mobile device while in use. A laser source projects structured light toward a forward path of the mobile device through the DOE. The structure light includes a transverse baseline and at least one transverse computational line. Then a lens is used to capture images of the structured light. When there is obstacle in a forward path of the mobile device, an image processing unit makes comparisons and performs computation according to changes in position and distance of the image of the respective transverse computational line relative to the X axis and the Y axis of the transverse baseline. Thus the relative position and distance of the obstacle in the forward path is checked in a real time manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Path detection system and path detection method generating laser pattern by diffractive optical element","description":"A path detection system and a path detection method generating laser patterns by a diffractive optical element (DOE) are revealed.
