ELECTROMAGNETIC LENS 

The electromagnetic lense can display magnetic radiation. This model has 16 sensors. Each sensor is composed of a loop and a detector whose bandwidth is between 1 and 440 MHz. The detected signals are then sampled from synchronously triggered by an internal trigger. The visualization is performed with leds positioned above each sensor. Two potentiometers are used to adjust the low threshold and the high threshold to always get the
maximum visible dynamics.
