Measurement sensors have an emitter and a receiver for measuring the width or the position of an object.
There are two methods; the light intensity variation method that identifies changes in the amount of light received and the CCD method that uses a CCD on the receiving element.
Light intensity variation methodLight is emitted parallel to the receiver from the emitter, and this parallel light is collected in the receiving element through the receiver lens. If there is a light interrupted object within the parallel light, then the light is interrupted and the amount of light received changes.
|
CCD methodLight is emitted parallel to the receiver from the emitter, and the linear CCD image sensor on the receiver receives the light.
|
Shading calibrationThe CCD method measurement sensors have variations in the distribution of light intensity from the semiconductor laser that is the light source and the CCD image sensor has variations in sensitivity to the light received. Therefore, the distribution of light-receiving sensitivity becomes uneven. In order to equalize it, the LD series (LD-C60) has the shading calibration function.
