LiTra HSR

LiTra HSR

HSR stands for High Spectral Resolution. Together with our LiTra-Technology, the LiTra HSR module enables the detection and differentiation between Mie and Rayleigh scattering. Our modules contain the complete optical system, i.e., a narrowband reference laser, a pulsed single-frequency laser, the telescope and detection by optical superposition (heterodyne or coherent detection).

Advantages of the LiTra HSR

• Coherent High Spectral Resolution Doppler lidar
• Possible wavelengths: 532 nm and/or 1064 nm
• Combined detection of Mie and Rayleigh scattering
• Available with pulse energy from mJ level to 100s of mJ
