Rotation system for optimal panoramic optical mapping

Panoramic optical mapping experiments use a single camera setup (Redshirt camera) to capture changes in electrical activity of rabbit hearts. A rotational system was developed that enables standardised rotation of a mounted rabbit heart.
Panoramic optical mapping experiments use a single camera setup (Redshirt camera) to capture changes in electrical activity of rabbit hearts.
During each experiment the rabbit heart is mounted within a Perspex chamber and the chamber is rotated both clockwise and anti-clockwise through a number of angles to acquire images from three different perspectives.
One shortcoming of this experimental design is the accuracy of the rotation angles, especially when the chamber is currently rotated by hand. Therefore, a rotational system was developed that enables standardised rotation. One of the key advantages is the ability to translate switched excitation changes to precisely defined steps, where each step would equate to rotating the chamber by a predefined angle.
