Lighting device for light transit time measuring system for photonic mixer detector camera, has evaluation unit and temperature sensors arranged on light source in close proximity, where temperature sensors differ in their active principles

摘要

The lighting device has a light source (12) having two temperature sensors (60,61) and an evaluation unit (100), which is connected with the temperature sensors by two interfaces (110,20). The temperature sensors are arranged on the light source in close proximity. The interface characteristics differ in their active principles or the two temperature sensors differ in their active principles. The temperature sensors have different temperature accuracy or temperature resolution. The interfaces have different analog to digital converters.
