摘要
The measurement of human skin temperature provides vital physiological information about human health status. In this paper, an application of digital holography has been demonstrated to measure human hand skin temperature. A volume phase holographic grating based digital holographic interferometric system has been used in a lensless Fourier transform configuration to measure the temperature of human hand skin. The presented system is non-contact, noninvasive, fast, compact, robust, requires lesser number of optical components, simple to align, and is easy to use.
