The Relationship

Linear displacement sensor is a component, which can convert the displacement into electrical signals, and is used to measure the relative motion between components. Because the relationship between output of sensor and stroke power is nonlinear and it may be affected by external factors, the circuit should be compensated and the sensor should be calibrated. In this research, the LED formed light knife in the mechanical slit, lighting on the sensitive CCD array, and the relationship between displacement and CCD photosensitive arrays can be founded. CCD is the discrete components, which has avoided the nonlinear problem. At the same time, because the CCD output is digital, it reduced the measurement time, so that linearity, accuracy, stability, greatly are improved greatly.

Measured Time

In order to time grating measurement principle application to the field of optical measurement, a uniform scan coordinate system by using photosensitive element of timing driven is presented to convert the displacement detection of the object into measured time difference. According to the conversion principle of relative motion coordinate systems of time grating, when view the photosensitive element of linear CCD as a uniform scanning coordinate system, view the spatial side by side and timing of mutually staggered on the two linear CCD as a stationary coordinate system, after measured the time difference variation of the output electric signal on the different CCD for the same object, size and direction of the relative displacement of the object would be made by multiplying time difference variation and scanning speed. With the calibration of the Renishaw laser interferometer for the developed linear CCD displacement sensor, the measuring errors are controlled within after error correction in the effective measuring range of 600.05mm. This realizes the idea of time measuring space in the field of optical.
