DETECTION APPARATUS, LIDAR, CHIP, AND TERMINAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18452403 titled 'DETECTION APPARATUS, LIDAR, CHIP, AND TERMINAL DEVICE
Simplified Explanation
The present disclosure describes a detection apparatus that uses a continuous laser beam and modulation techniques to detect targets in a detection area. Here are the key points:
- The detection apparatus includes a light source that emits a continuous laser beam.
- A modulator is used to modulate the continuous laser beam, resulting in a first laser beam that contains a carrier signal and symmetric side band signals.
- A first wavelength selector allows only the side band signals to pass through, while preventing the carrier signal from passing through. This results in a second laser beam.
- An optical transceiver emits the second laser beam to a detection area and receives a first echo signal, which includes the side band signals.
- The first side band signal is used to detect a target in the detection area.
Potential applications of this technology:
- Security systems: The detection apparatus can be used in security systems to detect the presence of intruders or unauthorized individuals in a specific area.
- Industrial automation: This technology can be applied in industrial automation processes to detect the presence or movement of objects in a production line.
- Environmental monitoring: The detection apparatus can be used in environmental monitoring systems to detect the presence of specific substances or pollutants in the air or water.
Problems solved by this technology:
- Improved detection accuracy: By using modulation techniques and selectively filtering the side band signals, the detection apparatus can provide more accurate and reliable detection of targets.
- Enhanced sensitivity: The use of a continuous laser beam and modulation allows for increased sensitivity in detecting targets, even in challenging environments.
- Reduced false alarms: The ability to selectively filter the side band signals helps to reduce false alarms by focusing on the specific signals related to the target.
Benefits of this technology:
- Increased efficiency: The detection apparatus offers a more efficient and effective way of detecting targets compared to traditional detection methods.
- Versatility: The technology can be applied in various industries and settings, making it a versatile solution for different detection needs.
- Cost-effective: The use of a continuous laser beam and modulation techniques provides a cost-effective solution for target detection, with improved accuracy and sensitivity.
Original Abstract Submitted
The present disclosure relates to detection apparatuses. One example detection apparatus includes a light source configured to emit a continuous laser beam, a modulator configured to modulate the continuous laser beam from the light source module to obtain a first laser beam including a carrier signal and symmetric side band signals, a first wavelength selector configured to allow at least one side band signal in the symmetric side band signals to pass through and prevent the carrier signal from passing through to obtain a second laser beam, and an optical transceiver configured to emit the second laser beam to a detection area, and receive a first echo signal for the second laser beam. The first echo signal includes the at least one side band signal, and a first side band signal is used to detect a target.
