Limitation of direct visual assessment using human’s eyes leads to development of many optical devices to help assessing skin condition. One of the common devices used in skin assessment is dermatoscopy, which basically is a digital microscope used to magnifies skin profile by utilizing light interaction with skin surface. However, this method has certain limitation. It cannot yield the exact depth or height information, thus it is not sufficient enough for specified needs. Another method to acquire depth information of skin topography is by measurement of light transmission through transparent skin replica made from a silicon gel. Therefore, this method requires contact with respondent’s skin during replication. Through this paper, development of a method involving projection of structured light is presented as non-contact microscopic skin imaging. The system, built of commercially available devices, consists of a projector and a camera configured in certain angles. The processing consists of phase extraction using phase shifting interferometry (PSI) and phase unwrapping process to obtain wrapped phase and absolute phase value respectively. Experimental work was done on different areas of the skin surface each represents different skin roughness to test the feasibility of the system. Quantitative analysis was done by texture analysis based on entropy calculation to compare intensity and phase images.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Digital microscopes,Microscopic measurement,Phase unwrapping,Phase unwrapping process,Phase-shifting,Phase-shifting interferometry,Skin imaging,Structured light projection[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Microscopic Skin Imaging,Phase Shifting,Phase Unwrapping,Structured light projection[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1007/978-3-319-19452-3_20[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
