==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.


==Original Abstract Submitted==

A measurement apparatus includes a light source that emits frequency-modulated light, an interference optical system that separates the light into reference light and output light and generates interfering light, a photodetector that receives the interfering light and outputs a detection signal corresponding to an intensity of the interfering light, a storage device that stores correcting data for use in correction of the detection signal, the correcting data being each associated with a corresponding one of different operating states of the light source, and a processing circuit that sends out a control signal to the light source, corrects the detection signal based on one or more pieces of correcting data selected from among the correcting data according to the operating state of the light source, and generates measurement data on a distance to and/or a velocity of a physical object based on the detection signal, and outputs the measurement data.
