Abstract
A method for operating an optical detection device provided for monitoring at least one monitoring region is disclosed. The method includes actuating at least one light-emitting element to transmit a light signal, receiving at least one reflected light signal using at least two monitoring regions of at least one receiver, and using at least one received light signal to determine at least on receive variable. The eye safety of the detection device is checked by configuring at least one of the receiving regions as a measurement receiving region and at least one of the receiving regions as a test region, generating at least one measurement receive variable that characterizes a quantity of light captured in one measurement time interval, and generating at least one test receive variable that characterizes a quantity of light captured in one test time interval.
