We project a time-varying, intense (>100 μJ/cm 2) optical pattern onto a silicon wafer, which spatially modulates the transmission of synchronous pulse of THz radiation.
Unlike X-rays, terahertz radiation is not ionizing radiation and its low photon energies in general do not damage living tissues and DNA. Some frequencies of terahertz radiation can penetrate several millimeters of tissue with low water content (e.g., fatty tissue) and reflect back. Terahertz radiation can also detect differences in water content and density of a tissue. Such methods could allow effective detection of epithelial cancer with an imaging system that is safe, non-invasive, and pai… WebTerahertz cameras New physical principle employed Operates at frequencies (0.05 – 0.7 THz), where most common materials are transparent 256, 1024, 4096 pixels models are available — to …
