An optoelectronic distance sensor with slant componenthaving a spacerbonded on a mother substrateis disclosed. The spacerhas slant surface for receiving one or more optoelectronic components, such as an optical sensor, that are mounted at an angle to the mother substrate. Such electronic componentsare bonded on a daughter substratewhich attaches to the spacerat the slant surface. The optoelectronic assemblycan be manufactured at chip-level, including by one ore more of exemplary methods disclosed herein.

Optoelectronic distance sensor

An optical displacement sensor for measuring distance or surface displacement of an object by surface profile scanning includes an optical source, a first optical detector and a second optical detector. The optical source is located intermediate the first and second optical detectors. The first and second optical detectors are arranged to collect light emitted by the optical source when scattered by and/or reflected from the object.

Optical displacement sensor and distance measuring apparatus

A method of sensing movement or proximity of objects by optical reflection is provided. The method includes the steps of transmitting a train of optical pulses towards a destination, sensing optical pulses reflected from the destination, and sensing and evaluating movement or proximity characteristics of objects at the destination with reference to variation in pulse width between transmitted and reflected optical pulses.
