Computer aided designing software not only the possibility to speed up the process of putting a new model into production and improve the quality of the products, but also reduces material costs and labour intensity, ensuring an elastic change of the assortment. The designing of clothes includes a row of processes and one of the most time and labour consuming is constructing. A construction displays the layout (pattern) of the surface of the body (garment). As it depends on correct anthropometric data, it is very important to get ones right. The use of 3D surface scanning technologies to produce digitized representations of the human anatomy has the potential to help change the way a wide range of products are designed and produced. Every scanning device is equipped with optic (light) appliances to ensure non-contact measuring. Measurements acquired by 3D scanning device should be checked out for compliance with CAD systems for automatized pattern making procedure. The paper introduces the experiment with scanned data usage in CAD pattern making. The project aims to implement scanned data values in the CAD/CAM individual measurement list for acquiring individualized pattern blocks.

A scanning device for a space-based environmental monitoring system has been investigated. The main attention is paid to the study of the parameters of the angular motion of the mirror of the scanning device, the uniformity of rotation of which largely determines the quality of the image of the Earth's surface. The principle and results of measuring the parameters of the mirror rotation carried out in a wide angular range are considered. The measurements were performed using a dynamic goniometer-autocollimator, which has been calibrated at the State Standard of Plane Angle Unit GET 22-2014. The repeatability of the average angular velocity of the scanning device mirror and the repeatability of the initial scanning angle are calculated. Nonstationarity in mathematical expectation and variance in random deviations of the angular motion of the mirror from the linear law of scanning is noted. The use of wavelet analysis revealed the frequency of excitation of oscillations in the low-frequency region of the spectrum. The possibility of using the a dynamic goniometer-autocollimator for measuring not only the angular position of the scanning device mirror, but also the angular velocity is shown.
