Laser range finding: How it works?<\/div>
\n

Pulsed laser range finder<\/strong> is based on measuring the difference in properties of the transmitted and back-reflected light<\/strong> from the target. The target changes the properties of the incident light and the back-reflected light is analyzed in the receiving equipment. Modulight manu\u00adfactures range-finding lasers for various market segments.<\/p>\n<\/div><\/div>\n

The distance measurement<\/strong> techniques are required in determining the height, width, distance, volume or movement of the target.\u00a0 Applications for the technique are laser radar<\/strong> speed measurements, traffic safety<\/strong>, laser profiling<\/strong> of target dimensions, weapons simulation, aero\u00adplane \/ satellite positioning<\/strong> and security area monitoring<\/strong>. Modulight\u2019s laser boasts a high peak-power and a short rise-time \u2013 laser characteristics which are important for high performance solutions.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n

Laser range finding applications set several requirements for the laser device. High output power<\/strong> is required at the same time in very short pulses<\/strong> of even picosecond range. However, the required power is defined by the distance and reflectivity of the target. High power can be achieved by constructing several emitter stacks or by increasing a single emitter dimensions. Light pulses up to 120-150 Watts<\/strong> can be generated using Modulight\u2019s laser diodes at 905 nm<\/strong> wavelength range. Though comparably lower output power with 1550 nm<\/strong> can be achieved, these lasers benefit in applications, where eye-safety is in key role<\/strong>. Modulight is pioneering in the 1550 nm range-finding lasers.<\/p>\n
