Claim One:
1. A method of static scaling of an original pattern in a predetermined size for obtaining said original pattern in another size in holographic lithography, the method comprising the steps of: providing an original pattern; generating a final virtual digital hologram of the original pattern through a sequence of mathematically calculated steps with participation of virtual coherent light source having a predetermined wavelength λ 1 ; producing an actual hologram on the basis of the virtual digital hologram of the original pattern; virtually determining a minimal wavelength λ min and a maximal wavelength λ max of the allowable wavelength variation range in which scalability is possible with substantially homotetic transformation; providing an actual laser light source with the wavelength λ 1 variable in the range between λ min and λ max , where λ min is the minimal wavelength and λ max is the maximal wavelength at which the homotetic transformation is possible; selecting a wavelength λ 2 in the range between λ min and λ max and setting the actual laser light source for operation on the wavelength λ 2 ; and producing the original pattern in another size by using the actual laser light source with the wavelength λ 2 .
