近接覚・触覚コンボセンサにおける周波数変調プローブ光を用いた近接計測手法の検討

抄録

We have developed a single sensor which can detect proximity and multi-axial touch force for smart- manipulation control of delicate objects. In this work, a measurement technique with modulated probe light to reduce of the environmental noise for proximity sensing has been reported. The white LED as probe light was switched at 150 Hz. Although the sensor output includes environmental noise from power source and room light, it is demonstrated that the proximity distance can be distinguished as amplitude of frequency component at 150 Hz.
