Abstract We report the first proof-of-principle demonstration of resonant optical gyroscope with reflector that we have recently proposed. The device is very different from traditional gyroscopes since it uses inherent coupling between clockwise and counterclockwise propagating waves to sense rotation. Our confirms our theoretical analysis simulations. also demonstrate a novel method biasing using orthogonal polarization states. simplicity structure readout method, theoretically predicted...

A proof-of-principle demonstration of a novel method background subtraction for optical coherence tomography is presented using full-field time-domain set-up. This single-shot based on time-averaged sampling sinusoidal phase modulation in the reference arm. It can significantly suppress motion artifacts as well entirely eliminate phase-noise induced errors that corrupt images obtained other methods. When used with Fourier domain set-ups, this technique also arbitrarily strong autocorrelation...

Expensive cameras meant for research applications are usually characterized by the manufacturers and detailed specifications [1] available them. Suppliers of inexpensive do not provide such information about their cameras. This data set provides acquisition speed noise characteristics acquired from a monochrome 1.2 megapixel CMOS camera, QHY5L-II M [2]. The source code provided along with this [3] can also be used to acquire similar other QHY enables use cost-effective scientific in fields,...

Sparse representation of images acquired from Magnet Resonance Imaging (MRI) has several potential applications. MRI is unique in that the raw are complex. Complex wavelet transforms (CWT) can be used to produce flexible signal representations when compared Discrete Wavelet Transform (DWT). In this work, five different schemes using CWT or DWT tested for sparse which form complex values, separate real/imaginary, magnitude/phase. The experimental results on real in-vivo show appropriate CWT,...

The proof-of-principle demonstration of a simple, yet effective method autocorrelation artifact removal for optical coherence tomography (OCT) is presented using custom-designed parallel spectral-domain OCT (SD-OCT) instrument. Our real-time based on time-averaged sampling sinusoidal phase modulation in the reference arm. Unlike other existing methods, our technique can completely eliminate arbitrarily located, strong artifacts.

In this paper, we introduce a novel time-averaged sampling method that can be used in low-cost, camera-based, line-field, spectral domain optical coherence tomography (SD-OCT) device. We demonstrate when with an automated subtraction and magnitude based averaging scheme is analogous to lock-in detection, enhance the usually poor dynamic range SNR. The technique unique as it effectively eliminates arbitrarily located, strong autocorrelation artifacts, robust against blemishes camera or...

ABC-OCT, Affordable B-scan Camera-based Optical Coherence Tomography, implements Fourier-Domain Tomography with real-time display using cross-platform C++ and the OpenCV framework. The software can be compiled current versions of GCC for *nix/Mac Microsoft®Visual Studio Windows. Full functionality ABC-OCT needs camera SDK from QHYCCD a to connected; but code easily modified support other drivers, as is shown by an included demo version which use any installed webcam. made available under MIT...

A proof-of-principle demonstration of a novel averaging technique for determining the amplitude vibration human tympanic membrane (TM) in-vivo, along with visualization its curvature and thickness in real-time, using very low-cost, custom-built, line-field spectral-domain optical coherence tomography device is presented. Unlike other vibrometry techniques that measure phase field, our method does away need expensive, higher than Nyquist frame-rate, cameras. In spite challenges measuring...
