Hemoglobin localization in erythrocytes is shown to lead to a decrease of their apparent absorption coefficient in the blue spectral range. This effect is quantitatively evaluated by using analytical relations. The replacement of erythrocytes by equi

We have elaborated and evaluated a new high-precision method of automated establishment of the position of an object. Unlike the method using laser theodolites, the desire object is defined not by a specular reflector, but a laser beam directed upwar
