First Claim
Patent Images
1. A module for use in an optical detection system for detecting an object within a detection area, comprising:
- a first light-generating unit, comprising;
a first light source for emitting a first collimated light beam; and
a first light-converting lens configured to convert the first collimated light beam into a first sheet of light entering into the detection area, wherein when the object is within the detection area, the object may intercept and reflect part of the first sheet of light thus producing a first reflected light; and
a detection unit, comprising;
a guiding lens configured to receive and guide the first reflected light; and
a detector configured to receive the first reflected light beam guided by the guiding lens generated by an object thereby forming an image of the object on the detector.
