Abstract: The temperature-measurement instrument proposed uses an optical system (4) to produce an image, on a detector (1), of the IR radiation emitted by a measurement point (2a) on the object (2) whose temperature is to be measured. The instrument also includes a sight (5) with diffractive optics (5b) which produces a light-intensity distribution pattern (6) indicating the position and size of the measurement point on the object.

Abstract: A remote temperature and/or temperature difference measuring device comprises a measuring circuit (13) having a sensor (14) for sensing the heat flow (14) from an area on the surface (30) of a body, and a portable housing (2) for said sensor and also a device (17) for determining the area of analysis. Said measuring circuit (13) includes: a memory circuit (35) connected to the heat sensor; a storage input device such as a push-button (36) for storing, at any given moment and in said memory circuit, a signal from said heat sensor, said signal being thereafter a reference signal; a comparator (33) of which one of the inputs receives the output signals from the heat sensor (14) while the other input is connected to said memory circuit (35) providing a reference signal, whereby said comparator outputs a signal which corresponds to the difference between said reference signal and said heat sensor output signal; and an indicator device (34) connected to the output of the comparator for producing a signal which corresponds to the above mentioned difference. The device can be used to measure the temperature on the surface of a human or animal body.

Abstract: An optical sensing system which generally comprises an infrared sensor (12), and a curved diffraction-limited window (14) disposed in front of the sensor such that the optical axis (16) of the sensor is parallel to and displaced from the symmetry axis of the window. The window has an inner radius of curvature which is non-concentric with the outer radius of curvature in order to remove the optical power of the window. Additionally, the window is provided with an aspheric profile outer surface (20), in order to correct for spherical aberrations in the window. The window is made out of germanium and is particularly useful for a sensor which has an 8-12 micron infrared radiation detection band width.
