Laser Doppler Flow

For advanced measurements of micro-vascular blood flow in tissue using laser Doppler technology, BIOPAC offers a Laser Doppler flow amplifier. This amplifier delivers a low power beam of laser light down an optical fiber to the tissue being studied. The amplifier then analyzes the Doppler shift created by moving red blood cells and outputs a channel indicating blood flow expressed in Blood Perfusion Units (BPU). On a second channel the amplifer simultaneously outputs the tissue remittance (Backscatter) from 0 to 100%. When used with BIOPAC electrodes, AcqKnowledge software, the MP150 data analysis and acquisition hardware platforms, transducers and other system components, this amplifier is an element of a complete data acquisition and analysis system.
