Abstract

We report on the development and application of terahertz spectral imaging in burn diagnosis, using our new Portable HAndheld Spectral Reflection (PHASR) Scanner. The PHASR Scanner features a fiber-coupled housing, which provides an alignment-free strategy for the placement and operation of the THz optics. Image formation is achieved through telecentric beam steering over a planar surface through a custom f-θ scanning lens. Electronically Controlled Optical Sampling can be implemented for high THz trace acquisition rates and a simultaneously recorded error signal can be used to calibrate the signals for accurate measurement. This scanner allows for a constant spatial resolution over a wide field of view and rapid acquisition of full THz-TDS spectra in clinical and operating room settings.
