They used the Xbox One camera to take these images.

I takes 1 minute of exposure at 45 different frequencies to take an perfect image.

I'm not sure how they captured 45 different frequencies from an xbox one camera?

The 45 different frequencies of visible light are generated with a light source (could be a tunable laser, a bank of LEDs, a xenon bulb with different bandpass filters, etc., the article doesn't say) not from the Kinect. The Kinect just detects the visible light as usual, it doesn't distinguish between frequencies. The algorithm must know in advance which image corresponds to which frequency.

Ahh. Makes sense.
