Optical delay stage

WebNov 26, 2024 · One of the key elements of terahertz time-domain spectrometers is the optical delay line. Usually it consists of a motorized translation stage and a corner reflector mounted on its top.... WebIncoming audio signal is converted into mechanical vibrations by an input transducer (a spring exciter). A similar transducer is used at the output stage to convert the spring's vibrations back into audio signal. Even a short impulse can cause extended vibrations – this is how the traditional reverb effect is achieved.
