Picked up another light source. My previous broadband purchase was a UV light <\/a>, and since I was deficient on the other side of the visible spectrum, I grabbed an IR source LED flashlight. I snuck into the lab to measure the spectrum, because we have an analyzer that covers 600-1700 nm. Just popped the flashlight onto the input jack (for fiber) and that coupled enough light in to make a measurement.<\/p>\n

Here’s what it looked like:
\n\"ando\"<\/p>\n

The early scans were smooth, so I’m not sure if the couple of dips in there are a result of some setting I changed, or if it’s a real effect (perhaps of heating up \u2014 the flashlight gets warm after a while, and this is a scan of the output after it was on for a few minutes)<\/p>\n

This isn’t the first (nor, I expect, the last) test of something mundane, just because the equipment is available. A few years back there was a rumor that the US $20 bill had an RFID chip in it<\/a>, located in Andrew Jackson’s eye, as “evidenced” by bills burning at that position when microwaved. A colleague and I tested that with a network analyzer, since an RFID chip should have a strong absorption feature on resonance. Nada. Not surprisingly, it’s an urban legend. (I swear it’s not there. Trust me: I work for the government)<\/p>\n","protected":false},"excerpt":{"rendered":"
