Abstract: A system including an image capture system with a sensing efficiency that varies over a field of view of the image capture system may employ shaped illumination to compensate for the variation in the sensing efficiency. An illuminator may be configured to illuminate the field of view of the image capture system with illumination shaped to have higher intensity where the sensing efficiency is lower, e.g., at the periphery of the field over view. The imaging system may thus provide image data with more uniform signal-to-noise ratios. Image data from an illuminated scene may be manipulated using data from a non-illuminated scene to produce improved image data.

Abstract: A system can include a light emitting diode (LED) and a transparent structure disposed over the LED. The transparent structure includes a first surface that reflects light extracted from the LED and incident on the first surface. The transparent structure also includes an exit surface opposite the first surface. The exit surface includes a first area that is textured to diffuse light over a first angular range and a second area that is textured to diffuse light over a second angular range. The second angular range is wider than the first angular range.

Abstract: A light-emitting device comprising VCSELs formed in a die. The VCSEL distribution is characterized by an essentially linear decrease in VCSEL density over the die from a highest VCSEL density in a first die region to a lowest VCSEL density in another die region. The VCSELs share a common anode and a common cathode for collective switching of the plurality of VCSELs. A method of manufacturing such a VCSEL die is also described.

Abstract: A light source includes a light-emitting diode or device (LED) and an optic mounted over the LED. The LED emits a first radiation pattern that is non-rotationally symmetric about a first axis. The optic collects the first radiation pattern and projects a second radiation pattern that is rotational symmetric about a second axis and has a peak intensity that is angled from the second axis.
