Electric and Near-Field Acoustic Detection, A Monograph
نویسنده
چکیده
The articles concern my recent work on the electric sense of sharks and rays. I have greatly advanced my theory of electromagnetic orientation, its theoretical foundations, and its application to the animals. I have furthermore developed a guided-approach algorithm explaining how sharks and rays cue in on the source of an electric field. Moreover, I have discovered in the electroreceptors a novel new means of amplifying the weak electric field signals, while at the same time attenuating the sensor noise.

متن کاملOptically trapped non-linear particles as probes for scanning near-field optical microscopy
We use the frequency doubled light from an optically trapped lithium niobate particle for non-intrusive scanning near-field optical microscopy. The detected power from this 50-100 nm diameter probe is currently tens of pW and is expected to approach nW with an improved detection system. The current experimental resolution is approximately 0.5 pm, while the ultimate theoretical resolution is 70-...
متن کاملA Design of Acoustic Security System in Near Field based on Paired Microphones and Automatic Video Camera
Many conventional security systems use visual information from a video camera. However, these systems may not be able to acquire the important scenes in the blind area of the video camera. Acoustic security systems can support conventional visual security systems with acoustic events detection. In our research, we focused on acoustic security systems in the near field, and we designed a prototy...
