4Pi spectral self-interference microscopy
Journal of the Optical Society of America A, 2007Spectral self-interference microscopy (SSM) relies on the balanced collection of light traveling two different paths from the sample to the detector, one direct and the other indirect from a reflecting substrate. The resulting spectral interference effects allow nanometer-scale axial localization of isolated emitters.

In full-duplex system, the key research of analog self-interference cancellation are self-interference channel and reconstruction circuit for self-interference suppression. In this paper, we measure the self-interference channel using the vector-based channel response measurement method, and analyze the effects of tap delay, tap interval, tap number ...

IBFD Indoor Self-Interference Channel Evaluation
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020In-Band Full-Duplex (IBFD) systems generate self-interference (SI) that is highly dependent on the environment surrounding each node. The design of various SI mitigation techniques requires an understanding of the potential SI channels that may be encountered in practical scenarios.

Alleviating self-interference in MANETs
29th Annual IEEE International Conference on Local Computer Networks, 2004The interference range in multi-hop ad hoc networks (MANETs) is typically twice as large as the transmission range. This phenomenon causes packets of a multi-hop flow to interfere with each other as they are relayed over the multi-hop route. This interference, an instance of the notorious hidden terminal problem, is caused by simultaneous transmissions

2021 IEEE Radio Frequency Integrated Circuits Symposium (RFIC), 2021
Self-interference (SI) mitigation is critical for full-duplex and frequency-domain duplex systems. Canceller noise and linearity limits the SI power that can be tolerated at RX input. A dual-path SI cancellation scheme is presented where the noise and distortion from the canceller are addressed through a differential noise-cancelling path. The proposed

Biological applications of spectral self-interference
SPIE Proceedings, 2004An original technique, Spectral Self-Interference Fluorescence Microscopy (SSFM), can determine the location of fluorescent markers above a reflecting surface with sub-nanometer precision. SSFM was used to resolve the position of a fluorescent marker bound to either the top or the bottom leaflet of a lipid bilayer -- the difference in distance is only ...

Electrochemiluminescence Self-Interference Spectroscopy with Vertical Nanoscale Resolution
Journal of the American Chemical Society, 2020Here we report an electrochemiluminescence (ECL) self-interference spectroscopy technique (designated as ECLIS) with spatial resolution in the normal direction of the electrode surface. Self-interference principally originates from the superposition of ECL emitted directly by luminophores and that reflected from electrode surfaces, resulting in a ...

4Pi Spectral Self-interference Fluorescence Microscopy
Frontiers in Optics, 2006Spectral Self-interference Fluorescence Microscopy using two opposing high numerical aperture objectives is proposed to precisely measure the axial position of fluorescent emitters. 5 nm change in the position of monolayer of fluorescent emitters was measured.
