An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor
Advanced Robotics Research, EarlyView.Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

Laser optical feedback tomography
Optics Letters, 1999We describe a new method for imaging in three-dimensional turbid media, laser optical feedback tomography. This technique is based on the resonant sensitivity of a short-cavity laser to frequency-shifted optical feedback from ballistic photons retrodiffused from the medium.

Laser optical feedback imaging insensitive to parasitic optical feedback
Applied Optics, 2007We present an optical architecture for the laser optical feedback imaging (LOFI) technique that makes it possible to avoid the effect of the optical parasitic reflections introduced by the optical components located between the laser source and the studied object. These reflections damage phase and amplitude information contained in the images.

Digital feedback optical vibrometer
2016 IEEE International Instrumentation and Measurement Technology Conference Proceedings, 2016Self-mixing interferometer allows to realize different kind of measuring systems, especially vibrometers. This work describes the design and implementation of a digital feedback-loop, acting on the laser pump current, able to lock the interferometer to half-fringe, and to measure the target vibration by estimating the feedback error signal. The digital

Micro-optic technology for the microfluidics feedback
2011 IEEE International Conference on Automation Science and Engineering, 2011The possibility of miniaturization of existing optical setups and technologies for the monitoring and control in microfluidics could represent a step toward the realization of a complete polymeric micro-optic-fluidic system. In this context the presented work involves the design and the optic simulation of PDMS micro-optic interfaces to reproduce the ...

Optical Feedback Buffering Strategies
2005This paper considers the performance of fixed and incremental feedback buffers in an optical switch, and compares this with the performance of a feedback buffer configuration implementing switchable delay lines. It is shown that for a medium sized switch the switchable delay line implementation outperforms the other configurations, although for a large

Optica Acta: International Journal of Optics, 1976
Some aspects of feedback technique in optical systems are examined. The eigenfunctions suitable for describing systems where both space and frequency limitations occur are discussed. Applications to the generation of super-resolving pupils and to the band unlimited restoration of images are presented.
