Kink modes of solar coronal structures, perturbing the loop in the direction along the line-of-sight (LOS), can be observed as emission intensity disturbances propagating along the loop provided the angle between the LOS and the structure is not ninety degrees. The phenomenon is based upon the change of the column depth of the loop (along the LOS) by the wave. The observed amplitude of the emission intensity variations can be larger than the actual amplitude of the wave by a factor of two and there is an optimal angle maximizing the observed amplitude. The observed amplitude depends upon the ratio of the wavelength of kink perturbations to the width of the structure and on the angle between the LOS and the axis of the structure. This phenomenon should be taken into account in the interpretation of wave phenomena observed in the corona with space-borne and ground-based imaging telescopes.
