   * Great read on the subject
+PICA
+  * "Well known that well working gates emit light during switching"
+  * "Emission is strongest when gate voltage is half of the drain voltage - the midpoint of the logic transition"
+  * "PICA uses a strobed, intensified detector to gather spatial information and time information"
+  * Specifically used a ring oscillator as an example of something it can image

     * Also will try silicon wafers as filters
   * Need to order another MU800? Check inventory
-    * Have 3: 1 for pr0nscope, 1 for inspection scope, 1 for brainscope

     * Could also use another one for k2scope and one for this
     * Order 2 more?

     * Think I have a small one
