Abstract: An optical system includes a housing that defines a first aperture and a second aperture different from the first aperture. At least one of the first aperture or the second aperture is defined by a peripheral surface having a plurality of inclined surfaces with respect to a center axis of the first aperture or the second aperture. In some cases, the peripheral surface may define a convex profile, may have a coating or a surface treatment, or may define other edge features that help mitigate optical crosstalk. The optical system may also include an array of light emitters disposed within the housing and configured to emit light through the first aperture and a light detector disposed within the housing and configured to detect a portion of the emitted light that is returned from a target and received through the second aperture.

Abstract: An electronic device such as a wristwatch may include a conductive housing. A corrosion-resistant coating may be deposited on the conductive housing. The coating may include transition layers and an uppermost alloy layer. The transition layers may include a chromium seed layer on the conductive housing and a chromium nitride layer on the chromium seed layer. The uppermost alloy layer may include TiCrCN or other alloys and may provide the coating with desired optical reflection and absorption characteristics. The transition layers may include a minimal number of coating defects, thereby eliminating potential sites at which visible defects could form when exposed to salt water. This may allow the electronic device to exhibit a desired color and to be submerged in salt water without producing undesirable visible defects on the conductive housing structures.
