Abstract
Optoelectronic modules (100) are operable to distinguish between signals indicative of reflections from an object of interest and signals indicative of a spurious reflection. Various modules are operable to recognize spurious reflections by means of dedicated spurious-reflection detection pixels (126) and, in some cases, also to compensate for errors caused by spurious reflections.
Claims9
An optoelectronic module comprising:
- a light emitter to generate light to be emitted from the module;
- a plurality of spatially distributed light sensitive elements arranged to detect light from the emitter that is reflected by an object outside the module;
- one or more dedicated spurious-reflection detection pixels;
- and
- circuitry operable to use a signal from the one or more dedicated spurious-reflection detection pixels to correct for a spurious reflection.
