Abstract
This paper deals with the real time reconstruction of a self-mixing displacement signal under devices with limited resources. By implementing a first-order-hold interpolation used in digital-to-analog converters, the signal recovery problem has been reduced to the efficient usage of an adaptive filter with high potential of parallelism, suitable to meet hard timing constraints, low memory usage and easily integrable with other mitigation algorithms of the physical phenomena proper to laser behavior, towards the creation of a robust embedded displacement sensor.
