Publications

The primary publication on this is Programmable Liquid Crystal Apertures and Filters for Photographic Lenses, which is a preprint of the Electronic Imaging 2021 paper by Henry Dietz presented January 20, 2021. We will link to the official copy once it is posted. The oral presentation slides provide a detailed overview.

3D Printed Parts

STLs will be posted shortly.

Software

The primary contribution here is a simple LCLV library for Arduino-compatible microcontrollers. This LCLV library is now available at https://github.com/aggregate/LCLV.git, and provides for either analog or digital control of the LCLV using two output pins to generate an AC control waveform. The library supports both timed shuttering and direct control of opacity.
