Abstract
According to an exemplary embodiment of the present invention, a system for measuring a distance is disclosed. The system includes: an LED light source configured to apply light to a target of which a distance is desired to be measured; a first splitter configured to partially reflect light applied from the LED light source; optical fiber configured to apply light passing through the first splitter to the target; and a second splitter configured to reflect light reflected from the target, and the system may further include: a first sensor configured to sense light reflected from the first splitter; and a second sensor configured to sense light reflected from the second splitter.
Claims15
A system for measuring a distance, the system comprising:
- an LED light source that applies an RGB light source configured to apply light to a target of which a distance is desired to be measured, wherein the LED light source applies white light in which R, G, and B are mixed;
- a first splitter configured to partially reflect light applied from the LED light source;
- an optical fiber configured to apply light passing through the first splitter to the target;
- a second splitter configured to reflect light reflected from the target;
- a first sensor comprising an RGB sensor configured to sense light reflected from the first splitter;
- and
- a second sensor comprising an RGB sensor configured to sense light reflected from the second splitter,
- a processor coupled to a memory device and configured to calculate displacement of the target by calculating a position of a peak point using a total amount of response in each of the first sensor and the second sensor based on values measured through the RGB sensors.
A system for measuring a distance, the system comprising:
- a sensor probe;
