Abstract:
1. An optical probe assembly that is configured to provide electric current to and receive electromagnetic radiation from a plurality of devices under test (DUTs), wherein the plurality of DUTs is on a substrate, the optical probe assembly comprising: a power supply structure that is configured to simultaneously provide the electric current to the plurality of DUTs; an optical collection structure that is configured to simultaneously collect the electromagnetic radiation from each of the plurality of DUTs and provide the electromagnetic radiation to an optical detection structure, wherein the optical collection structure includes a first optical collection device associated with a first device under test (DUT) of the plurality of DUTs, and a second optical collection device associated with a second DUT of the plurality of DUTs; and an optical baffle structure that is configured to decrease a transmission of electromagnetic radiation from the first DUT to the second optical collection device.
