Analyzing physical structure of skin using noninvasive method. Diagnosing state of body structure using correlation between chemical components and skin physical structure. Optimization image sensor for measuring skin structure using light. Analyzing method for living organic using light. Image processing technology for living organic using light.   Skin thickness measurement equipment using light which in product developing phase, allows diagnosing various diseases and provide further observation data and therefore tends to expand it's applications. Thus, applications for this technology is diverse; skin malignant tumor, malignant tumor, skin benign tumor to scleroderma, hardening dedmatous, skin shrivel after steroide topical anointment, skin paranoia, fibroma and lipoma. Therefore understanding of skin structure and information for skin thickness are inevitable for practical clinical application based on status of the disease. Even though Calipers or Micrometer method applied noninvasive equipment are prevailed for skin analyzing, there are limitations; inaccurate result and unable to using for specific part. On the other hand, radiation-using method is more accurate while this has drawbacks in high cost and dangerous from radiation usage. Recently, ultrasonic measuring device with superior quality resolution is continuously developed, still price for this equipment too high to become commonly used. In this vein, we are approaching from different measuring principle and using noninvasive type, aiming to develop the most accurate and safe equipment.
