| 英文摘要 | Reflective optical sensors. A reflective optical sensor for sensing the presence of an object can include a reflective sensor package having a first cavity and a second cavity. The first and second cavities can be located side-by-side in the sensor package. A vertical cavity surface emitting laser (VCSEL) can be located within the first cavity for producing an optical emission. An optical receiver can be located within the second cavity and configured to receive at least a portion of the produced optical emission that is reflected from the object such that when the reflected emission is above a threshold strength the object is determined to be present. The optical receiver can be a shunt phototransistor and can include reverse bias protection. |
