Of great importance in neurosurgery is guiding Deep Brain Stimulation (DBS) needle probe which needs precise and detailed navigation within the brain tissue. PS-OCT is a powerful imaging tool that can be used to obtain detailed information within the tissue at different depths based on the low coherent light interferometry and birefringence properties of the tissue by exploiting polarimetric methods. It is noteworthy to mention that PS-OCT exhibits great resolution and sensitivity based on the tissue birefringence related parameters (retardation and optic axis orientation) especially for the precise placement of DBS probe in the subthalamic nucleus (STN), which is entirely surrounded by myelinated fiber bundles that are highly birefringent. In general, images obtained using this system can provide a spatial map of the anisotropic structure of the tissue.","PeriodicalId":6789,"journal":{"name":"2021 Photonics North (PN)","volume":"49 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91269353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variation of electrical property with temperature as well as with UV irradiation was studied. The substrate temperature seems to affect the electrical property of the deposited films. The electrical resistivity decreases as the substrate temperature decrease. The effect of UV irradiation on samples were systematically investigated with different substrate temperature. All samples were exposed to UV irradiation for one hour. By exposing samples to UV irradiation, electrical resistivity was found to decrease as a function of time. A correlation is established between, UV irradiation, and the substrate temperature of the MoO3 films. This dependence of the substrate temperature is important in the point of view of applications, where the we can control the resistivity of the MoO3 film depending on the application needed.","PeriodicalId":6789,"journal":{"name":"2021 Photonics North (PN)","volume":"17 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83835686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
