Real-time pollen monitoring using digital holography

Remote monitoring of building oscillation modes by means of real-time Mid Infrared Digital Holography.

Non-destructive measurements of deformations are a quite common application of holography but due to the intrinsic limits in the interferometric technique, those are generally confined only to small targets and in controlled environment. Here we present an advanced technique, based on Mid Infrared Digital Holography (MIR DH), which works in outdoor conditions and provides remote and real-time i...

Real-time terahertz digital holography with a quantum cascade laser

Coherent imaging in the THz range promises to exploit the peculiar capabilities of these wavelengths to penetrate common materials like plastics, ceramics, paper or clothes with potential breakthroughs in non-destructive inspection and quality control, homeland security and biomedical applications. Up to now, however, THz coherent imaging has been limited by time-consuming raster scanning, poin...

Real-time quantitative phase reconstruction in off-axis digital holography using multiplexing.

We present a new approach for obtaining significant speedup in the digital processing of extracting unwrapped phase profiles from off-axis digital holograms. The new technique digitally multiplexes two orthogonal off-axis holograms, where the digital reconstruction, including spatial filtering and two-dimensional phase unwrapping on a decreased number of pixels, can be performed on both hologra...

Real Time Temperature Distribution Measurement of a Microheater by Using Off-Axis Digital Holography

Real Time Monitoring using sEMG

A Wearable Electromyography device includes the advantage of Electromyography (EMG) sensors and provides a wired or wireless human machine interface (HMI) for interacting with computing systems and attached devices associated with electrical signals generated by specific movement of the patient’s muscles. Following initial automated self-calibration and positional localization processes, measur...
