Noncontact temperature measurement of human hand skin using volume phase holographic optical element based digital holographic interferometer

Optics and Lasers in Engineering, 2022
Abstract Measurement of surface temperature of human body skin is one of the basic and standard diagnostic tool for health management. The temperature of the human body is a vital sign of health status and it is used for medical diagnosis. Generally, contact type temperature sensors are used for temperature monitoring; however, accuracy of these ...

Photopolymer materials for volume phase holographic optical elements [PDF]

International Conference on Space Optics — ICSO 2016, 2017
Volume Phase Holographic Gratings (VPHGs) cover a relevant position as dispersing elements in spectrographic instrumentations with low and medium resolution. This is due to their unique properties especially in terms of diffraction efficiency. These devices have to provide dispersion, resolving power, bandwidth and diffraction efficiency according to ...
