I made a transmission hologram today, in memory of this week's 50th anniversary of the first one by Leith & Upatnieks. Really enjoyed the simplicity of it, and the connection with their groundbreaking work all those years ago. The setup is on a small Newport table pulled from a dumpster, on an old drafting table used by GTE Sylvania in the '60s. The pics below show the table and setup in a bedroom, processing on the sink, and where I put it among some old lasers. It's a porcelain bunny I got on a family vacation in LA probably around 1966 (in Laguna Beach), in front of a white square and next to the reference mirror.
