Classification: CPC B  G | IPC B  G

Claim 20:
21. An object sensor test system comprising:
a sensor comprising a receiver configured to receive a simulated optical signal and generate at least one measurement signal representative of the simulated optical signal, and a processing chain that includes a plurality of processing components configured to process the at least one measurement signal generated in response to the simulated optical signal to generate processed test data corresponding to the simulated optical signal,
wherein the processing chain comprises a plurality of outputs,
wherein each output is configured to output respective processed test data from the processing chain, wherein the respective processed test data corresponds to one or more processing components located upstream from the output in the processing chain, and
wherein the sensor further comprises a first test interface configured to receive a control signal indicating a selected output from the plurality of outputs in the processing chain and selectively extract the respective processed test data at the selected output based on the control signal, wherein the first test interface is separately coupled to each output of the plurality of outputs by a respective signal line for receiving the respective processed test data; and

a test bench comprising a second test interface configured to communicate with the first test interface, the test bench configured to transmit the control signal to the first test interface, receive the respective processed test data from the sensor, compare the respective processed test data with expected data to generate a comparison result, and determine that a segment of the processing chain is operating normally or abnormally based on the comparison result.
