Toward multimode-fiber shape sensing
Optics Letters, 2023We demonstrate machine-learning assisted dynamic tracking of the shape of a multimode fiber whose spatial configuration is manipulated by the movement of three linear stages. The data source used for the analysis is the coherent speckle pattern of light that has made a round trip in the fiber.

Sensing surface shape by touch
[1993] Proceedings IEEE International Conference on Robotics and Automation, 2002The design and construction of a tactile sensor that has been developed to measure the surface shape of objects held between the fingers of a robot gripper are described. A robotic tactile sensory workcell has been assembled to investigate touch-mediated grasping and object manipulation.

The mechanical forces that shape our senses
Development, 2022ABSTRACTDeveloping organs are shaped, in part, by physical interaction with their environment in the embryo. In recent years, technical advances in live-cell imaging and material science have greatly expanded our understanding of the mechanical forces driving organ formation.

Shape Sensing using the ShArc Technique
Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems, 2020ShArc is a new, geometric technique for real-time measurement of complex curves. These sensors have a flexible strip that can be dynamically formed into different shapes in a plane. Unlike traditional bend sensors which provide only a single measure of angle, inexpensive ShArc sensors provide detailed information about their precise shape.

Geometric Sensing of Known Planar Shapes
The International Journal of Robotics Research, 1996Industrial assembly involves sensing the pose (orientation and position) of a part. Efficient and reliable sensing strategies can be developed for an assembly task if the shape of the part is known in advance. In this article we investigate two problems of determining the pose of a polygonal part of known shape for the cases of a continuum and a finite

Compressive sensing of parameterized shapes in images
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008Compressive sensing (CS) uses a relatively small number of non-traditional samples in the form of randomized projections to reconstruct sparse or compressible signals. The Hough transform is often used to find lines and other parameterized shapes in images.

This monograph records a series of experiments on the completion clouds of a base language model, read through a sparse autoencoder. A prefix is sampled many times over; each continuation is reduced to the concept-features it activates at layer 20 of Qwen3.5-9B-Base; and the shape of the resulting cloud of fingerprints is measured.
