N2 - An integrated optical micro-displacement sensor was developed that uses the beam diverging from a vertical cavity surface emitting laser (VCSEL). The sensor consists of a VCSEL of 1.5 mm× 1.5 mm× 1 mm that is surrounded by three photodiodes. It can measure the linear distance traveled or the tilting angle for an external mirror. The resolution is 10 nm for a measurement range of 0.4 mm, or less than 40 nm for a wider measurement range of 1.8 mm. The full range of the measurable tilting angle is 5°. The sensors can be incorporated into devices with micro-mirrors, such as integrated scanning microscopes.
