OPTICAL ENCODER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18547649 titled 'OPTICAL ENCODER
The optical encoder described in the patent application consists of a light source, a reflector, and a light receiver. The reflector has multiple reflection areas, including M-code areas, that reflect light from the light source based on the M-code areas.
- The reflector has M-code areas that contain first and second code information on different faces with varying inclination structures.
- The light receiver performs a photoelectric conversion on the reflection light received from the reflector.
- The light receiver is divided into first and second light-receiving groups, with each group receiving light reflected from the corresponding face of the M-code areas.
- The positions of the light-receiving elements in the first and second groups are shifted from each other in one direction.
Potential Applications: - Position sensing in robotics and automation - Motion control systems in manufacturing - Optical navigation systems in consumer electronics
Problems Solved: - Accurate position detection in various applications - Improved reliability and precision in optical encoding systems
Benefits: - Enhanced performance in motion control applications - Increased accuracy in position sensing - Greater reliability in optical encoding technology
Commercial Applications: Title: Advanced Optical Encoder Technology for Precision Motion Control This technology can be utilized in industrial automation, robotics, CNC machines, and other precision control systems. The market implications include improved efficiency, accuracy, and reliability in various industries.
Questions about Optical Encoder Technology: 1. How does the inclination structure of the M-code areas contribute to the accuracy of the optical encoder?
The inclination structure helps differentiate between the first and second code information, allowing for precise position detection.
2. What are the potential cost savings associated with implementing this optical encoder technology in industrial applications?
By improving accuracy and reliability, this technology can reduce downtime and maintenance costs in industrial settings.
Original Abstract Submitted
Optical encoder includes a light source, a reflector, and a light receiver. Reflector has a plurality of reflection areas that include M-code areas and reflects a light from light source by one or more areas, corresponding to n-bits, of M-code areas. Light receiver receives a reflection light from reflector to perform a photoelectric conversion on reflection light. M-code areas has a first face corresponding to first code information and a second face corresponding to second code information and having an inclination structure different from that of first face. Light receiver has first and second light-receiving groups. First light-receiving group includes a plurality of first light-receiving elements receiving reflection light reflected from first face. Second light-receiving group includes a plurality of second light-receiving elements receiving reflection light reflected from second face. Positions of first light-receiving elements and positions of second light-receiving elements are shifted from each other in one direction.
