vooroppervlakspiegel

Vooroppervlakspiegel, also known as a surface acoustic wave (SAW) mirror, is an optical component used in spectroscopy to reflect light signals. The device is typically constructed using a piezoelectric material, such as lithium niobate or quartz, on which a periodic pattern of metallic strips is deposited.

These metallic strips act as electrodes, causing the piezoelectric material to generate surface acoustic waves when an alternating current is applied. The waves then interact with the incident light, resulting in a controlled reflection of the light signal. The properties of the SAW mirror, such as the frequency and amplitude of the generated acoustic waves, can be adjusted to optimize the performance of the device for specific applications.

The vooroppervlakspiegel is often used in various spectroscopic techniques, such as infrared spectroscopy and optical coherent tomography, to modulate and detect light signals. Its compact size, stability, and wavelength flexibility make it a valuable component in a number of optical and spectroscopic systems.

The operation of the SAW mirror can be understood based on the principles of surface acoustics. When a light beam hits the mirror, it interacts with the generated acoustic waves, resulting in modulation of the light signal. The reflected light beam exhibits a frequency modulation, which can be used for signal processing and detection.

The vooroppervlakspiegel offers advantages in terms of its linear operation, absence of scattering, and ability to maintain signal quality over a wide range of frequencies. Its customizability through variations in design parameters allows for a tailored performance in specific spectroscopic applications.
