This invention discloses a probe structure and a thermometer, simply-structured but easy to use for users in a dark environment. The technique solution adopted in this invention is a probe structure, including a probe main body, a temperature sensor module and an optical assembly. The probe main body includes a detection end and a configuration end. The detection end is configured for touching or approaching an object. The configuration end is configured for connecting to an external thermometer body. The probe main body has a chamber for storing the temperature sensor module. The optical assembly is positioned at the configuration end. The optical assembly includes at least one lamp, a lamp panel and a light transmitting component. The at-least-one lamp is positioned at the lamp panel and the light transmitting component is disposed at the periphery of the lamp panel. Light emitted by the lamp passes through the light transmitting component.

An apparatus for measuring body core temperature includes a light guide with an internally reflective tube. The light guide is coupled to an earpiece, and has a lens or an aperture positioned at one of its ends. A sensor is positioned at the other end of the light guide, and a processor is coupled to the sensor. The sensor senses infrared radiation from an infrared source at the end of the light guide, and the processor determines a temperature of the infrared source at the end of the light guide via a transfer function that correlates a measure of the infrared radiation observed by the sensor and an effect of radiation of the light guide.

A temperature detection device (10) for a vehicle heater detects a fluid temperature. The device includes a temperature sensor (12) as well as a contact element (14) with a first side (16), around which the fluid can flow in at least some sections, and with a second side (18) facing away from the first side (16). The temperature sensor (12) is configured as a radiation sensor. The contact element (14) is arranged relative to the temperature sensor (12) such that at least a part of the radiation emitted from the second side (18) of the contact element (14) can be received by the temperature sensor (12).
