Classification: CPC B  G | IPC B  G

Claim 13:
14. A method of testing an object sensor comprising a processing chain that includes a plurality of processing components configured to process at least one measurement signal generated in response to a reflected signal, the method comprising:
transmitting a control signal to a test interface of the object sensor, the control signal indicating a selected output from a plurality of outputs in the processing chain;
transmitting a simulated optical signal to a receiver of the object sensor;
generating electrical signals as test data by the receiver in response to the simulated optical signal;
processing the electrical signals by a processing chain of the object sensor to generate processed test data;
selectively extracting the processed test data at the selected output of the plurality of outputs in the processing chain based on the control signal, wherein the selected output is downstream from the receiver in the processing chain;
comparing the processed test data with expected data to generate a comparison result; and
determining that a segment of the processing chain is operating normally or abnormally based on the comparison result.
