Accu-Arc sensors are a new class of low-cost, high-speed, and ultra-precise angle sensors. These sensors have no moving parts and angular precision is directly related to SNR:

1. No moving parts results in very low cost with the ability to accurately and precisely measure very small angular motion.

2. Angular precision being related to SNR results in numerous configurations that can enable applications requiring extremely high precision, such as 0.1 arcsecond (0.5 microradians) or better.
