The control section includes an analog-front-end (AFE) to convert analog signals of the photodetectors to digital signals and an arithmetic processor to detect a rotating posture of the scale plate based on the digital signals. The control section simultaneously emits lights from the photoemitters and simultaneously receives the lights by the corresponding photodetectors. The control section then executes the following data processing for each photodetector one by one in sequence: outputting the analog signals representing an entire area of a light-receiving area of one of the photodetectors and outputting the digital signals converted by the AFE to the processor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Angle detection device and survey instrument including the same","description":"An angle detection device include photoemitters, photodetectors, a scale plate disposed therebetween, and a control section to control them.
