Illumination: LED matrix, DPC, brightfield

Draft outline

Scaffold. Replace the bullet prompts with your own text and delete this banner when done.

How-to, for operators. Drive the LED matrix / ring for brightfield and computational contrast (DPC).

Brightfield​

  • Set intensity; the LED slider range; using a diffusor for even illumination.

LED matrix / ring patterns​

  • Selecting patterns; oblique illumination; the ring.

Differential phase contrast (DPC)​

  • What DPC needs (opposing half-patterns); how to run it; the output.
