Today, in the medical field, ultrasound is frequently used for both diagnostic and therapeutic purposes. Ultrasound waves are generated with the help of a transducer that can both emit high frequency sound waves and detect reflected echoes of them. In this way, by applying a gel that prevents the formation of air gaps between the transducer and the dermis, ultrasound enables the imaging of internal organs, the detection of a specific target, the ablation or disintegration of a tissue or a specific target. Thus, ultrasound imaging is a non-invasively method that is generally considered safe since it does not produce ionizing radiation. However, the requirement to move the transducer over the dermis, ie contact, can be a disadvantage of ultrasound imaging for some situations. In these cases, optical imaging, where light is used for imaging in medical applications, can be used alternatively. In optical imaging, non-ionizing radiation including visible, ultraviolet and infrared light is used. In this way, the patient's exposure to harmful radiation can be significantly reduced, and it can be used in the diagnosis and treatment of the disease. However, the major disadvantage of optical imaging can be its high cost. In this study, lateral shearing digital holographic microscopy (LSDHM) method is used for both providing a nondestructive, full-field and high-resolution imaging and reducing the cost which is the major disadvantage in optical medical imaging. In this context, it has been shown that optical medical imaging can be performed with low cost and less components with an exemplary imaging application.
