NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences01:17

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.
Linear time-invariant Systems01:23

Linear time-invariant Systems

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be calculated...

Voltammetric Techniques: Pulse Voltammetry

Differential-pulse voltammetry (DPV) is a type of voltammetry that involves applying a series of voltage pulses to an electrochemical cell while measuring the resulting current. In DPV, the differential pulse or small potential pulses are superimposed on a linear potential sweep. The magnitude of these pulses is typically small, often in the millivolt range. Each voltage pulse lasts a short duration, usually in the order of a few milliseconds, and is applied at regular intervals along the...
Pulse amplitude and quality01:17

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...
Oscillations In An LC Circuit01:30

Oscillations In An LC Circuit

An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by
Voltammetric Techniques: Linear-Scan (E vs Time)01:12

Voltammetric Techniques: Linear-Scan (E vs Time)

Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...

  • Optics and Photonics
  • Quantum Information Science
  • Electrical Engineering

Background:

  • Linear pulse-characterization techniques utilize electrically driven temporal modulators for high-sensitivity electric field measurement of optical pulses.
  • Precise synchronization of the electric-drive signal to the optical source is critical for accurate implementation.
  • Understanding the impact of relative synchronization jitter on experimental data and reconstructed electric fields is essential.

Purpose of the Study:

  • To investigate and quantify the effect of relative synchronization jitter on three linear optical pulse-characterization techniques.
  • To determine the tolerance of these techniques to timing variations between the optical pulse and the electric-drive signal.

Main Methods:

  • Derivations and simulations were performed for linear spectrography, spectral-shearing interferometry, and simplified chronocyclic tomography.
  • The impact of varying degrees of relative synchronization jitter was analyzed on the measured experimental traces and reconstructed electric fields for each technique.

Main Results:

  • Accurate electric field characterization was achieved for all three techniques even with relative jitter standard deviations several times the pulse duration.
  • The study quantifies the robustness of these linear techniques against synchronization imperfections.

Conclusions:

  • Linear pulse-characterization methods demonstrate significant resilience to synchronization jitter.
  • These findings support the practical implementation of these techniques in scenarios where perfect synchronization is challenging, enabling high-accuracy optical electric field measurements.
