RANGE FINDING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18492663 titled 'RANGE FINDING APPARATUS
Simplified Explanation
The patent application describes a range finding apparatus that uses light of different wavelengths for efficient range finding.
- Light source device emits light of a first wavelength and a second wavelength concurrently.
- Distance information is computed based on the time period from when range finding is started until incident of light on a pixel of a light receiving part is detected.
- A pixel array of the light receiving part includes a first pixel for light of the first wavelength and a second pixel for light of the second wavelength arranged two-dimensionally.
Potential Applications
- Autonomous vehicles for accurate distance measurement.
- Robotics for precise object detection and navigation.
- Surveillance systems for enhanced monitoring capabilities.
Problems Solved
- Improved accuracy in range finding by utilizing light of different wavelengths.
- Enhanced performance in various applications requiring distance measurement.
- Reduction in measurement errors and increased reliability.
Benefits
- Increased efficiency in range finding processes.
- Enhanced precision in distance measurement.
- Versatile applications in different industries for improved functionality.
Original Abstract Submitted
Disclosed in a range finding apparatus that can efficiently perform range finding that uses light of different wavelengths. The range finding apparatus comprises a light source device capable of concurrently emitting light of a first wavelength and light of a second wavelength that is longer than the first wavelength and computes distance information based on a time period from when range finding is started until when incident of light on a pixel of a light receiving part is detected. In a pixel array of the light receiving part, a first pixel configured to receive light of the first wavelength and a second pixel configured to receive light of the second wavelength are two-dimensionally arranged.
