Prototype Terahertz Imager Promises Biochem Advances (1 of 2)

Caption: The NIST terahertz imaging system reveals slight temperature differences, as shown in this post-processed image. The color scale ranges from blue indicating 301 K or 28.75 degrees C, to red indicating 302.5 K or 29.35 degrees C. The image was made of the test scene shown in the photo, a room-temperature ring on top of a warmer absorber material. Quantitative analysis shows the current system can distinguish structures with dimensions as small as 4 millimeters, to be significantly improved in the future.
