An infrared thermometer has a field of view selected so that the temperature of the crop growing in a field is accurately measured. The infrared thermometer may be mounted on a support pole in a field to substantially continuously monitor the foliage temperature of the growing crop. In one preferred embodiment, the infrared thermometer comprises and instrument housing structure provided with an infrared telescope mounted on a turntable that scans through an angle of the field, while an electronic circuit simultaneously integrates the output of the infrared telescope. The angle to be scanned is selected by the user in accordance with his needs. In another embodiment, the infrared thermometer comprises a novel sensor head block including an aperture which provides a wide, elongated oval field of view for an infrared sensor provided therein. In both embodiments, the elongated oval field of view has a width that is at least four times its height. The elongated oval field of view is selected to substantially block the infrared radiation emitted by background sources such as the sky and the ground.

Agricultural infrared thermometer

An apparatus for use in determining the temperature of or at a specific area by measuring the infrared radiation from that area through the use of a reflector structure to direct the radiation from the area to an infrared detector can be improved by using a laser to provide two light beams which are directed so as to intersect at a distance from the apparatus corresponding to the principal focus of the reflector structure.
