US Patent 7,952,374

An apparatus for analyzing an integrated circuit to which one or more test signals are applied. An example apparatus includes an objective lens that views reflections from the integrated circuit, a device that houses at least two optical fibers, a component that receives reflections from the objective lens and directs the received reflections to the device, and a photo-diode that receives a reflection received by the device. The apparatus includes a beam splitter that directs reflections from the integrated circuit to a detector. A processing device generates an image signal based on a signal received from the detector and a display outputs an image based on the image signal. The component includes a scan mirror that reflects the collimated reflections to a collimating lens that focuses the reflections from the scan mirror toward the device.
