APPARATUS AND METHOD FOR MEASURING DISTANT TO AND/OR VELOCITY OF PHYSICAL OBJECT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18461398 titled 'APPARATUS AND METHOD FOR MEASURING DISTANT TO AND/OR VELOCITY OF PHYSICAL OBJECT
Simplified Explanation
The patent application describes a measurement apparatus that uses frequency-modulated light to measure the distance and/or velocity of a physical object. Here are the key points:
- The apparatus includes a light source that emits frequency-modulated light.
- An interference optical system separates the light into reference light and output light, generating interfering light.
- A photodetector receives the interfering light and outputs a detection signal corresponding to the intensity of the interfering light.
- A storage device stores correcting data associated with different operating states of the light source.
- A processing circuit sends a control signal to the light source, corrects the detection signal based on selected correcting data according to the operating state of the light source.
- The processing circuit generates measurement data on the distance and/or velocity of the physical object based on the corrected detection signal and outputs it.
Potential applications of this technology:
- Distance and velocity measurement in automotive applications, such as collision avoidance systems or adaptive cruise control.
- Industrial applications, such as robotics or automated manufacturing, where precise distance or velocity measurements are required.
- Aerospace applications, such as aircraft navigation or landing systems.
Problems solved by this technology:
- Provides a more accurate and reliable method for measuring distance and velocity compared to traditional methods.
- Allows for correction of detection signals based on the operating state of the light source, improving measurement accuracy.
- Enables real-time measurement of distance and velocity, allowing for immediate response in various applications.
Benefits of this technology:
- Improved accuracy and reliability in distance and velocity measurements.
- Real-time measurement capability for immediate response in critical applications.
- Versatility in various industries and applications due to its ability to measure both distance and velocity.
