Abstract
This article deals with problematic of measuring of optical beam in free space optics (FSO). The professional FSO link was created between two buildings standing 1,5 kilometers apart from each other. Signal passing through the atmospheric media between optical heads is affected. This happens due to effects in atmospheric media. This article describes creating of the device for measuring the intensity of optical beam in 2D space and its subsequent rendering into 3D graph.
Highlights
The free space optics (FSO) link consists of two optical heads operating in full duplex mode, both as transmitter and receiver (Fig. 1)
Optical head is usually placed on the roof of buildings, but it can be placed in windows
The power of the Gaussian beam is given as the product of half of the maximal intensity and area of a circle with a radius equals to the radius of a central beam [2], [9], [10]
Summary
The FSO link consists of two optical heads operating in full duplex mode, both as transmitter and receiver (Fig. 1). These optical heads are situated against each other and must be in direct line of sight. Intensity distribution of Gaussian beam in the transverse plane corresponds to a circularly symmetric Gaussian function, where the optical axis is axis of symmetry. Where w0 is half-width at its narrowest point, z is observation plane distance, z0 is Rayleigh distance This distance can be described as longitudinal direction of propagation of the waist to the point, where the transverse cross-section area is doubled, z0 can be calculated [9], [10].
