In addition, a novel imaging technique is described and demonstrated. It is not based on the same semiconductor laser system, but instead utilizes an erbium doped fiber amplifier. The imaging technique enables a non-contact, non-invasive method of imaging without strict requirements on a stable laser source or complicated electronics.The two current signals from the detectors are viewed on an oscilloscope (OSC, Tektronix TDS 724D), which has a 500 MHz bandwidth. The two oscilloscope ... is 300 /mi, which is in perfect agreement with the size of the pinhole. ... 6.8, the reference and measurement arms are recombined optically via a 50/50 fiber coupler.
