title = "Design of a laser transmittance measurement system",
abstract = "A laser transmittance measurement system designed to measure the transmittance of lasers passing through propellant plumes with wavelength 0.808μm, 1.06μm and 10.6μm is introduced in this paper. The transmission method is applied as the measurement method and the lasers are modulated with certain frequencies. By measuring the laser impinging intensity and the laser emerging intensity of the plume, the transmittance of the plume can be calculated. A microprocessor is applied for system controlling and data processing. Meanwhile, the measurement results are transmitted to a computer through the serial port, corrected automatically and shown in real time. As a result the data can be saved and printed for future analysis. Based on the results of system performance trial, this system fulfills the accuracy, stability requirements as designed.",
