OPTICAL SENSOR, METHOD FOR PRODUCING OPTICAL SENSORS, OPTICAL ENCODER, TORQUE DETECTION DEVICE, AND ELECTRIC POWER STEERING DEVICE |
摘要 |
<p>An optical sensor, an optical encoder, a torque detection apparatus, and an electric power steering apparatus less affected by fluctuations in the amount of detected light and with an improved resolution are provided. The optical sensor includes a first polarizing layer that splits incident light to light with a first polarization direction, a first photoreceiver that receives first polarized light split by the first polarizing layer, a second polarizing layer that splits the incident light to light with a second polarization direction, and a second photoreceiver that receives second polarized light split by the second polarizing layer. The first photoreceiver and the second photoreceiver are positioned alternatingly and spaced uniformly with each other.</p> |
