Product Overview

Product Features

BSLD80 series products are frequency modulated continuous wave (FMCW) radar products operating at 76-81GHZ,

supporting four-wire and two-wire system applications, with a maximum scale of 120M, and a blind area of 0.8M at full

scale. Due to its higher operating frequency and shorter wavelength, it is particularly suitable for solids and mixed reaction

medium, and offers unique advantages in dusty, harsh environments.

No blind area.

· Very good transient performance: the pulse width of the electromagnetic pulse in the 76-81GHZ band can be narrowed to the

sub-picosecond (PS) level, so it can be used to carry out time-resolved research on a variety of materials to measure the

molecular structure; through the sampling and measurement techniques, it can effectively suppress the interference of the farinfrared background noise.

· There is a very wide bandwidth: 76-81 GHZ band pulsed sources typically require only a few cycles of electromagnetic

oscillation, close to the vibrational and rotational energy levels of many biological macromolecules, dielectrics, semiconductors,

superconductors, and molecular vibrational energy levels of thin film materials. Therefore, 76-81 GHZ band spectroscopy can

be an effective means of detecting information about materials in the millimeter-wave band, and is well suited for measuring

the absorption spectra of materials, which can be used for qualitative identification applications.· Coherence: coherent currentdriven dipole oscillation generation or coherent laser pulse nonlinear differential frequency effect generation;

· Low energy: Millimeter-wave photons have an energy of only a few milli-electron volts, which makes them less susceptible to

damage as X-rays do not ionize and destroy the detected material.

· Strong penetrability: Strong penetrability for non-polar materials, many non-metallic non-polar materials absorb less radiation

in the 76-81GHZ band, therefore, it can be used to detect the internal structure of materials. For example, ceramics/cardboard/

plastic products/foam etc. are transparent to electromagnetic radiation in this band.

· Easily absorbed by polar molecules: 76-81 GHZ band has less scattering in non-homogeneous substances, enabling detection

and measurement of water vapor content, etc. They can also be analyzed for compositional studies or quality control.
