The controller acquires a first detection current from a light-receiving element when supplying a first drive current to a light-emitting element and acquires a second detection current from the light-receiving element when supplying a second drive current to the light-emitting element. The calculator generates a signal indicating deterioration of the light-emitting element when a reference value and an aging value satisfy a deterioration judgment condition, the aging value being a ratio between the first detection current and the second detection current. The detection accuracy of the light emitting and receiving apparatus is thereby improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting and receiving apparatus and method of diagnosing deterioration","description":"A light emitting and receiving apparatus includes a controller and a calculator.
