Ⅰ. Relationship among OFSCN® Fiber Bragg Grating Strain Sensor, OFSCN® 광섬유 브래그 격자 변위 센서, OFSCN® Fiber Bragg Grating Stress Sensor and OFSCN® Fiber Bragg Grating Deformation Sensor
The OFSCN® Fiber Bragg Grating Strain Sensor is the most common and widely used sensor among OFSCN® Fiber Bragg Grating Sensors. It shares a direct correspondence with OFSCN® 광섬유 브래그 격자 변위 센서, OFSCN® Fiber Bragg Grating Stress Sensor and OFSCN® Fiber Bragg Grating Deformation Sensor, so they have the same structure.
1. Relationship between OFSCN® Fiber Bragg Grating Strain Sensor and OFSCN® 광섬유 브래그 격자 변위 센서
The OFSCN® 광섬유 브래그 격자 변위 센서 is an application that extracts parameters from OFSCN® Fiber Bragg Grating Strain Sensor. The relationship is given by: Displacement = Total Length × Strain. Therefore, the structure of OFSCN® 광섬유 브래그 격자 변위 센서 is the same as OFSCN® Fiber Bragg Grating Strain Sensor, with the difference lying in the calibration formula, which corresponds length to wavelength values.
2. Relationship between OFSCN® Fiber Bragg Grating Strain Sensor and OFSCN® 광섬유 브래그 격자 응력 센서
The OFSCN® 광섬유 브래그 격자 응력 센서 is a calculating application of OFSCN® Fiber Bragg Grating Strain Sensor. The relationship is given by: Measured Stress = Elastic Modulus of the Measured Object × Strain. Therefore, the structure of OFSCN® 광섬유 브래그 격자 응력 센서 is the same as OFSCN® Fiber Bragg Grating Strain Sensor. However, as the tested materials differ after purchasing the OFSCN® 광섬유 브래그 격자 응력 센서, the calibration formula corresponds micro-strain to wavelength values.
3. Relationship between OFSCN® 광섬유 브래그 격자 Strain Sensor and OFSCN® 광섬유 브래그 격자 Deformation Sensor
'OFSCN® Fiber Bragg Grating Deformation Sensor' is not a precise term. Deformation can be expressed as displacement - in this case, corresponding to OFSCN® 광섬유 브래그 격자 변위 센서, or it can be expressed as strain - in this case, corresponding to OFSCN® Fiber Bragg Grating Strain Sensor.

OFSCN® 광섬유 브래그 격자 Strain Sensors can also be classified based on the number of FBG strain measurement points, such as single-point and multi-point sensors.
또한 튜브형, 웨이퍼형(표면 실장형), 표면 FBG 변형 센서를 포함하여 다양한 캡슐화 재료, 구조 및 배포 프로세스를 기반으로 분류할 수 있습니다.
