PURPOSE: An optical apparatus for detecting information and information detection apparatus is provided to improve distribution efficiency by totally recognizing and identify the barcode of products. CONSTITUTION: A collimation optical unit(310) includes a light emitting unit and a light reception unit including a first limited optical system(210). The collimation optical unit converts light emitted from a sensor unit(100) into a first unlimited optical system(250). The sensor unit recognizes a code provided to an object. A reflection unit(350) forms a second unlimited optical system(260) by reflecting the light of the first unlimited optical system. An emission optical unit(330) converts the light of the second unlimited system into a second limited optical system(220). |
