Measurements performed with an Airyscan laser phase microscope showed the possibility of localisation of structural elements of a surface with a large gradient of the profile height and linear dimensions as small as 25 — 40 nm, which is 10 — 15 t

Information encoded in DNA implicitly determines the sequence of processes at different organizational levels of living matter. Optical microscopy is a major source of knowledge about processes in living cells. Further progress in biology to a large

A laser phase microscope with a conventional optical system was used to obtain images of latex spheres 100 nm in diameter, of various viruses, and of other microscopic objects. Satisfactory images were obtained when the focusing was exact ( ~30 nm) a

A more accurate formulation of the Abbe theory is presented using well-known open resonator results, namely, field representation in terms of the eigenfunctions of the optical system viewed as a segment of an equivalent lens waveguide; and the use of

The metabolic component of refractivity is considered as an example of a quantifying parameter for the 'vitality' of cells and organelles. It is shown that intracellular processes can be studied by the dynamic phase microscopy method, which provides

A review is given of the work carried out abroad and in the Soviet Union on gas-jet laser cutting. The physical basis of the cutting process is considered and the solutions are given of the thermal problems on the assumption that heat sources have po

An automatic unit was developed for gas-laser cutting of materials. A CO2 laser with an output power of about 500 W and a commercial EM-703 program-controlled X–Y plotter were the main components of the unit. The principal parameters of the unit ar
