The reflected light of the wavelength that was focused on the surface of the measurement object passes through the fiber and the spectroscope in the Controller converts the wavelength to a distance. The height is detected based on the wavelength.
This achieves a much more compact design and much greater immunity to noise than triangulation models and or previous confocal models. There is no needs for a lens drive mechanism or electronic parts in the Sensor Head, even though they were considered to be standard in previous confocal models. The Sensor Head contains the special set of lenses that separates white light into different colors and the Controller contains the white LED light source, and the spectroscope and processor that convert the color of the reflected light to a distance. As a result, only the color of light that is focused on the measurement object is returned, allowing the distance from the Sensor Head to the measurement object to be calculated based on the color of the reflected light. Measuring rods and circumference measuring tapes are relatively simple devices in routine medical work they still have to fulfill challenging clinical requirements.
The white light from the LED is focused at different points for each color (i.e., wavelength) due to a special set of lenses in the OCFL module in the Sensor Head. Height measuring systems When the quality is right, so are the measurements.
