Abstract
An impairment detection system is provided and includes an emitter, first and second beam selectors, a reference reflector, a sensor and a control module. The emitter is configured to emitter a first light signal. The first beam selector is configured to forward the first light signal to a touch probe. The reference reflector is configured to reflect the first light signal received from the first beam selector to generate a second reflected signal. The second beam selector is configured to receive (i) a first reflected signal from the touch probe based on reflection of the first light signal on an area of a person, and (ii) the second reflected signal. The sensor is configured to receive from the second beam selector the first reflected signal and the second reflected signal. The control module is configured to determine an impairment level of the person based on an output of the sensor.
