Thu, Sep 14, 2023Phase Detection with Lock-in Amplifier and Phasemeter
Precise and sensitive phase detections are often required for impedance and optics-based measurements. For example, measuring the phase shift between current and voltage reveals the complex impedance of a device or component. Very small displacements can be measured by the phase shift between...

Wed, Jun 21, 2023Noise Mitigation Strategies for Infrared Detection
When it comes to infrared measurements, a lock-in amplifier paired with a pulsed light source is an essential tool to increase the signal-to-noise ratio (SNR) for low light applications. This tech note highlights the advantages of using a lock-in amplifier with Hamamatsu’s InAsSb detectors and LEDs.
