Pulsed Laser Beam

The angular and temporal distributions of energy in the reflection of a pulsed laser beam from a sea surface depend on the diameter of the beam and on the wavenumber spectrum of the water surface. Theoretical expressions are derived for the influence on the reflection of the mean height and slope of waves in the illuminated area as well as the variation of the height and slope within this area. The results are applied to airborne lasers for wave height profiling, altimetry and water depth sounding. The optimum beam diameter depends on both the application and the wavenumber pectrum of the water surface.

The scanning of human body as a method for gaining human measurements has several preferences. The gathering of data is possible in a very short time. In comparison to manual measuring methods, scanning acquires a larger amount of measurements. There are several modes of gaining human body measurements using the scanning system: laser scanning, light beam scanning, etc. A research on the laser beam reflection capabilities on different textile materials has been performed. The description of laser reflections has been compared to the Lambert’s law’s characteristics. The matrix of material selection is made in the process of planning the experiment and all possible materials are presented in this matrix. Eight textile materials are chosen for the experimental work: six lingerie and two additional materials. A laser beam with an angle of incidence of 0º and 45º is used to make the experiment. The dependence of the results on the wavelength of laser beams has also been compared.
