Positional sensor for solar energy conversion device |
摘要 |
A positional sensor for a solar energy collection device includes a fine sensing device having first light-sensitive sensors supported above a base so that adjacent first light-sensitive sensors are oriented in mutually orthogonal directions at a sensor height above the base. The first light-sensitive sensors are positioned at oblique angles relative to the base. The sensor also includes a coarse sensing device having a light-opaque shield surrounding the first light-sensitive sensors that extends outwardly from the base to a height that is greater than the sensor height. The shield includes second light sensing devices directed outwardly from the shield and arranged so that adjacent second light-sensitive sensors are oriented in mutually orthogonal directions.
