要約(英語): According to earlier studies of distance-velocity sensors using the self-coupling effect of semiconductor lasers, the linearity of the triangular wave current that drives the semiconductor laser was poor. Therefore, the linearity of the triangular wave was improved using arbitrary waveforms to improve the accuracy of the measured values. However, multiple triangular waves were required for measurement; hence, the measurement was time consuming. Therefore, we changed the driving circuit of the semiconductor laser to a current spitting method to improve the linearity of the triangular wave current and conducted research on signal processing for mode-hop pulses, which are measured with a single pulse. Consequently, we devised a new method that enables single-pulse measurement while maintaining the measurement accuracy of the sensor. The experimental results indicated that distance and velocity can be measured with the same level of accuracy as the results obtained with multiple pulses to date.
