Abstract: FIELD: medicine.SUBSTANCE: method of measuring relative accommodation by tension and relaxation of accommodation in a constant state of vergence, wherein a patient is shown, at a minimum viewing angle, an image of two crossing rows with pairs of differently spaced pairs of identical figures with optotypes. Constant state of the vergence is controlled by the presence of a sensation in the patient of the binocular image in the form of three vertical rows. After that, relative accommodation "+" and "-" is measured. Observation is carried out by depicting a series of figures lined up in a line. Besides, inside the figures there are optotypes of different types located in the center, and the rows are arranged with the possibility of changing the angle between them. Measurement of the positive part of the relative accommodation is carried out in the zone of pre-plane fusion by adding to the optical correction to the distance of the reducing lens -2.5…-5.0, patient is asked to indicate the nearest figure with an optotype which is clearly perceived and without double vision, subtract 3.0D and the force of the reducing lens for mathematical re-calculation of the positive part of the relative accommodation with the reducing lens from the absolute accommodation parameter. To measure the negative part of the relative accommodation, a reducing lens +2.0D is used, the patient is asked to indicate the furthest figure with an optotype perceived clearly and without doubling, for mathematical recalculation of the negative part of the relative accommodation, the value of the absolute accommodation value is subtracted from 3.0D.EFFECT: application of the invention will make it possible to increase accuracy of measurement of relative accommodation and to provide reliability of perception of stereographic impression.1 cl, 4 dwg

Abstract: FIELD: hydro acoustics. 
     SUBSTANCE: invention relates to the field of hydroacoustics and is intended for determining the distance to an object noisy in the sea. Noise hydroacoustic signal of marine object is investigated, comparing it with forecast signal generated for set of assumed distances to object by determination of correlation coefficient. Analyzing the main and several local maxima of the dependence of the correlation coefficient on the assumed distance, several hypotheses are formed on the distance. Simultaneously several successive directions are measured on the object. For each distance hypothesis, the estimated tangential velocity component of the object is determined. As an estimate of the distance to the object, the hypothesis on the distance is selected, for which the value of the tangential velocity component does not exceed the maximum possible speed of movement of the real object. 
     EFFECT: exclusion of displacement error when determining distance to object in conditions of zonal structure of acoustic field.
