Melanoma skin cancer is one of the most lethal types of cancer due to comparably early development of metastasis. As preventative medical check-up, optical inspection using polarized light (dermoscopy) is the gold standard in medical practise. If a lesion is diagnosed to be suspicious, it is subsequently excised by a surgeon and analysed by means of histopathology. However, optical inspection so far...
Driven by demands from medicine and the life sciences, for example, a variety of new point of care tests (POCT) based on smartphones are currently investigated [e.g. 1]. For instance, in combination with an external electrical read out system smartphones have been applied for the monitoring of diabetes or, by employing the smartphone camera, for the interrogation of lateral flow tests.
With the advancement of illumination technology in automotive industry, significant amount of interest has arisen for laser based light sources for both front and rear end. While numerous amount of work has been done to incorporate laser based illumination for front lights [1], less attention has been paid towards rear and brake lights. Use of lasers as sources of illumination allows utilization of...
In this work different fibre optic sensors for the structural health monitoring of civil engineering structures are reported. A fibre optic crack sensor and two different fibre optic moisture sensors have been designed to detect the moisture ingress in concrete based building structures. Moreover, the degeneration of the mechanical properties of optical glass fibre sensors and hence their long-term...
Optical techniques are utilized in robot aided surgery as navigation tools to guide surgical instruments. The advantages are a reduction of severe damage during surgery and of post-surgical trauma. A common approach is to place spherical markers inside the operating field, which can be detected by a 3D imaging device, in order to determine the position of the patient with respect to the instrument...
