    Abstract: An eye-safe optoelectronic module includes a light source mounted on a support and operable to generate light along an emission axis. An eye-safe substrate has an eye-safe substrate refractive index and includes at least one diffusive surface. The eye-safe substrate is mounted such that the emission axis is intercepted by the diffusive surface. An optical assembly includes at least one optical element, is composed of an optical material and is mounted on the diffusive surface of the eye-safe substrate such that the optical material fills a diffusive surface of the eye-safe substrate. The optical assembly has an optical assembly refractive index that is substantially the same as the eye-safe substrate refractive index.

    Abstract: This disclosure relates to illumination modules operable to increase the area over which an illumination source, such as a vertical-cavity surface-emitting laser or light-emitting diode, illuminates. Such illumination modules include a substrate having electrical contacts, an illumination source electrically connected to the substrate, a collimation assembly operable to collimate the light generated from the illumination source, a translation assembly operable to translate light over an area, and a mask assembly. In various implementations the illumination source may be rather small in area, thereby reducing the cost of the illumination module. Some implementations of the illumination module can be used for the acquisition of three-dimensional data in some cases, while in other cases some implementations of the illumination module can be used for other applications requiring projected light.

    Abstract: An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array comprising a multitude of transmissive or reflective microlenses which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array of light sources for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N≧1. High-contrast high-intensity light patterns can be produced.

    Abstract: The present disclosure describes techniques for testing optical devices in a manner that, in some implementations, simulates the environment in which the devices will be used when they are integrated into the end-product or system. For example, one aspect includes providing a transparent sheet that is positioned near the optical device in a manner that simulates at least some aspects of the environment when the device is incorporated into the end-product or system. The testing can be performed, for example, while the optical devices are in production or at some other time prior to their being integrated into an end-product or system.
