Abstract
A radiation detector for axillary temperature measurement comprises a wand having an axially directed radiation sensor at one end and an offset handle at the opposite end. The radiation sensor is mounted within a heat sink and retained by an elastomer in compression. The radiation sensor views a target surface through an emissivity compensating cup and a plastic film. A variable reference is applied to a radiation sensor and amplifier circuit in order to maintain full analog-to-digital converter resolution over design ranges of target and sensor temperature with the sensor temperature either above or below target temperature.
