In 1986 was 16 and saved up enough for the sand box holography kit, but it came without the required developing fluid. I had a sand box table, my own laser its still sitting on my desk a Metrologic kit .05 mw that still works. Was several years later in college that was able to get the necessary chemicals to develop the 3 year old film from the kit. Worked great but the developing always was my weakness, just never developed the technique to do it properly (pun intended). The first one would come out really nice but the second would not ,due to the fluid would degrade during the time it took to make changes to the set up to get that perfect image.
Have picked up more film and lasers 200mw diode that really surprised me after using the Hene for many years the coherence length is almost unbelievable . But my wife is tired of asking me to clean up the kitchen after a night of developing and there are a few stains on the floor that are not going to come out. So after hesitating I tried the Litiho film. Here are my results. Less mess . did I mention there is no mess. I can see the image form during the exposures, which surprised me . Told my daughter who is always willing to help with an experiment that I did not think it would work since I could see the interference lines forming do to motion in the room. Will admit was very surprised to see the image when turned off the laser and the overhead light on. Not sure my days of staining the kitchen floor are over but it’s worth experimenting more.
