In this paper, the optical set-up and construction of the portable hand held holographic camera is described. The high output power (150 mW) semiconductor pig tailed laser diode as light source was used. The wavelength of the emitted radiation is 980 nm. Optical fiber elements have been used. The interferometry correlation methods was used for testing the possibility to measure the changes between the initial ideal fiber picture and current stage of fiber.
