Imaging fibre bundles for Fizeau-based optical coherence tomography [PDF]
, 2008 An OCT system incorporating a coherent fibre imaging bundle is described. Fibres are accessed sequentially by a beam focused onto the input face of the bundle, allowing 2D or 3D images to be acquired using point detection.

Phase-Modulated Standing Wave Interferometer
Micromachines, 2021 The actual technical implementation of conventional interferometers is quite complex and requires manual manufacturing. In combination with the required construction space defined by the optical setup, their applications are limited to selected measuring

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014 We propose a measuring technique for microflow based on the stochastic resonance phenomenon. The minute changed signal from the microflow hidden within the threshold of multi-threshold imaging sensors, such as CCDs, can be reconstructed using an external
