Today digital holographic interferometry (DHI) is considered a modern full-field non-destructive technique that allows generating 3D quantitative data of a wide variety of specimens. There are diverse optical setups for DHI that enable the study of specimens in static and dynamic conditions: it is a viable alternative to characterize a wide diversity of parameters in the micro and macro world by conducting repeatable, reliable and accurate measurements that render specimen data, e.g., displacements, shape, spatial dimensions, physiological conditions, refractive indices, and vibration responses. This paper presents a review and progress on the most significant topics, contributions and applications involving DHI for the study of different specimens such as: cells, bio tissues, grains, insects, and nano-structures. For most of the research work involving macro and micro specimens the wave-like source used in the measurements were photons from a laser, while the studies carried out in the nano regime used the wave-like nature of the electron.

skin temperature provides an important physiological information of human health which plays a vital role in several research and applied applications, particularly in surgery, pediatrics, and general emergency centers [1][2][3]. Human skin temperature is an indicator for disease diagnosis. During the global pandemic COVID-19 produced by the Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) virus [4] measurement of human body temperature has become a primary and critical parameter for identifying potential COVID-19 symptoms. Although in hospitals other patients, physicians, doctors, attendants, nurses, and visitors are the most common sources of cross-infections, the clinical thermometer should not be disregarded. Also, owing to the possibility of patient-topatient or cross-contamination, healthcare personnel are not advised to contact the patient for temperature measurement in order to avoid spreading the virus. Generally, contact-type temperature sensors such as mercury (Hg) in glass or electronic thermometer affixed directly to the underlying skin surface to acquire the temperature. However, the skin-sensor contact, sensor physical size, and sensor pressure limit the accuracy of *
