Abstract—Several research works exploring the potential of utilizing grayscale image for the measurement of many physical phenomena has been published. In this present paper we have designed a new linear displacement sensor utilizing the grayscale image. This sensor is based on temporal changes in the intensity of light by the movement of grayscale image with the linear displacement of target. The variation of light intensity detected in terms of voltage by the signal processing circuit (SPC). The output of SPC is fed to a microcontroller program to display the linear displacement of target directly. The experimental results are shown a satisfactory performance of the sensor for linear displacement in the range of 0mm to 40mm.
