Abstract: A LIDAR system has a laser emission unit configured to generate a plurality of laser beams. The LIDAR system also has an optical system configured to transmit the plurality of laser beams from the laser emission unit to a common scanning unit. The common scanning unit is configured to project the plurality of laser beams toward a field of view of the LIDAR system to simultaneously scan the field of view along a plurality of scan lines traversing the field of view.

Abstract: A temperature-forcing system and method for controlling the temperature of an electronic device under test comprises a temperature-forcing head, including a face positionable in thermal contact with the device, and an evaporator, in direct or indirect thermal contact with the face; and a refrigerant circulation subsystem, including a compressor, a condenser, a flow control device for inducing a pressure drop in the refrigerant, and a conduit circuit through which the refrigerant is flowable. The subsystem cooperates with the evaporator so as to define at least one closed loop through which a corresponding bi-phase refrigerant is circulatable, so that, during circulation, the refrigerant is maintained in a liquid phase between the compressor and the flow control device and in a gaseous phase while flowing through the evaporator. The temperature of the device is therefore switchable by the head at a rapid rate of 50 to 150 degrees Celsius per minute.

Abstract: A temperature-forcing system, for controlling the temperature of an electronic device under test, comprising— a temperature-forcing head, including a face configured to be put in thermal contact with the device and an evaporator, in direct or indirect thermal contact with the face; and a refrigerant circulation subsystem, including a compressor, a condenser and a metering device; wherein the subsystem is configured to circulate a bi-phase refrigerant, in closed loop fashion, through the evaporator so that, during circulation, the refrigerant is maintained at high pressure between the compressor and the metering device and at low pressure while flowing through the evaporator. More specifically, in the disclosed system the refrigerant, while flowing through the evaporator at a low pressure, is operative to dissipate heat therefrom by evaporation and the evaporator or any part thereof is formed as a heat exchanger.
