Optical positioning sensor

摘要

A sensor is disclosed that can include a light component in support of a first light source operable to direct a first beam of light, and a second light source operable to direct a second beam of light. The sensor can also include an imaging device positioned proximate the light component and operable to directly receive the first beam of light and the second beam of light and convert these into electric signals. The imaging device and the light component can be movable relative to one another. The sensor can further include a light location module configured to receive the electric signals and determine locations of the first beam of light and the second beam of light on the imaging device. In addition, the sensor can include a position module configured to determine a relative position of the imaging device and the light component based on the locations of the first beam of light and the second beam of light on the imaging device.

1. A sensor, comprising:
a light component in support of a first light source operable to direct a first beam of light, and a second light source operable to direct a second beam of light, wherein the second beam of light is non-parallel to the first beam of light; an imaging device positioned proximate the light component and operable to directly receive the first beam of light and the second beam of light and convert the first beam of light and the second beam of light into electric signals, wherein the imaging device and the light component are movable relative to one another; one or more elastic members that connect the light component to the imaging device, wherein the one or more elastic members are operable to facilitate relative movement of the imaging device and the light component; a light location module configured to receive the electric signals and determine locations of the first beam of light and the second beam of light on the imaging device; and a position module configured to determine a relative position of the imaging device and the light component based on the locations of the first beam of light and the second beam of light on the imaging device.
