An optoelectronic module including 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, and one or more dedicated spurious-reflection detection pixels.

Disclosed is a light receiving element including an on-chip lens, a wiring layer, and a semiconductor layer disposed between the on-chip lens and the wiring layer. The semiconductor layer includes a photodiode, a first transfer transistor that transfers electric charge generated in the photodiode to a first charge storage portion, a second transfer transistor that transfers electric charge generated in the photodiode to a second charge storage portion, and an interpixel separation portion that separates the semiconductor layers of adjacent pixels from each other, for at least part of the semiconductor layer in the depth direction. The wiring layer has at least one layer including a light blocking member. The light blocking member is disposed to overlap with the photodiode in a plan view.

The present disclosure describes systems and techniques for estimating a height of an object by processing wave signals transmitted from a detection device to the object and reflected by the object. In aspects, a detection device transmits wave signals, which propagate via a direct path and an indirect path via reflection over a reflecting surface, to be reflected by the object. Operations include measuring wave signals reflected by the object and generating measurement vectors and producing a spectrum of an estimated elevation angle of the object over the range. Further, the operations include estimating the height of the object from the spectrum. The length of the window can be determined by estimating the range interval covered by a full phase cycle of a phase difference between the direct path and the indirect path from a current value of the range and a current estimate of the height of the object.
