Single device for measurement of infrared or millimeter wave radiation

Creators

Description

A radiation measurement means is shown which has the capability of detecting radiation in both the millimeter wave, and the infrared, frequency regions. A basic self-oscillating Gunn diode is enclosed in a donut shaped silicon ring. The presence of infrared energy will create holes and electrons in the silicon material, altering its conductivity, and lower the power of oscillation. The realized drop in oscillating power identifies the infrared. Millimeter wave radiation is detected because an intermediate frequency is generated as the Gunn diode operates as a self-oscillating mixer of the new different frequency with its own oscillating frequency. Thus it is possible to detect signals from both ranges, in a single device
