Development of an optical micro-motion sensing system

Physiologic hand Tremor is a common trait among humans although it varies in amplitude and frequency from individuals to individuals. It is generally unnoticeable as its amplitude is small. The amplitude of hand tremor can worsen due to anxiety, fatigue or use of stimulants like caffeine. However, i...
