Abstract: An optical module includes an enclosure and an optical output assembly mounted on the enclosure. An emitter mounted in the enclosure is configured to emit a beam of light toward the optical output assembly. A connector, which includes two conductive layers separated by a dielectric layer, has a first side connected to the enclosure and a second side connected to the optical output assembly. An electrical trace disposed on the enclosure is connected to the first side of the connector so as to define a test circuit having a capacitance. Control circuitry is coupled to sense the capacitance of the test circuit, and configured to inhibit operation of the emitter upon sensing a change in the capacitance that exceeds a predetermined threshold.

Abstract: An optoelectronic assembly includes an integrated circuit (IC) chip including, on its front side, a photoconversion region and first electrical contact pads disposed alongside the photoconversion region. A circuit substrate contains a cavity into which the IC chip is inserted through the lower side and has a window opening through the upper side in communication with the cavity such that the photoconversion region of the IC chip is exposed through the window. The circuit substrate includes electrical circuit traces, which include second electrical contact pads disposed within the cavity alongside the window so as to contact the first electrical contact pads on the front side of the IC chip within the cavity. A base includes a stiff, heat-conducting material, to which the lower side of the circuit substrate is fixed. A malleable heat-conducting layer is compressed between the rear side of the IC chip and the base.

Abstract: An apparatus for testing diffraction or diffusion of a light beam is provided. The apparatus includes a photosensitive semiconductor, shaped to define an aperture. At least one anode, and a plurality of cathodes, are coupled to the semiconductor. An optical element, configured to modify an angular spread of a light beam that traverses the optical element, is disposed within the aperture. A detector is configured to detect electric currents that pass between the cathodes and the anode in response to a portion of the light beam exiting the optical element and hitting the semiconductor. Other embodiments are also described.

A first set of optical detectors is disposed in the first compartment and configured to receive a first redirected portion of the emitted light through the first aperture. A set of optical elements is disposed in the first compartment and configured to direct at least a portion of the emitted light or the first redirected portion of the emitted light. A second set of optical detectors is disposed in the second compartment and configured to receive a second redirected portion of the emitted light through the second aperture.

Abstract: Apparatus for optical sensing includes an illumination assembly, which directs first optical radiation toward a target scene over a first range of angles and second optical radiation over at least one second range of angles, which is smaller than and contained within the first range, while modulating the optical radiation with a carrier wave having at least one predetermined carrier frequency. A detection assembly includes an array of sensing elements, which output respective signals in response to the first and the second optical radiation. Processing circuitry drives the illumination assembly to direct the first and the second optical radiation toward the target scene in alternation, and processes the signals output by the sensing elements in response to the first optical radiation in order to compute depth coordinates of points in the target scene, while correcting the computed depth coordinates in response to the second optical radiation.
