We construct a quantum theory of free scalar fields in (1+1)-dimensions based on the deformed Heisenberg algebra , that admits the existence of both a minimal measurable length and a maximal momentum, where is a deformation parameter. We consider both canonical and path integral formalisms of the scenario. Finally a higher dimensional extension is easily performed in the path integral formalism.
