Abstract: A radiometer includes an integrally mounted digital camera aligned to image the energy zone of the radiometer. When digital photographs are taken they are time stamped and stored in memory. The images may be viewed on a viewer integrated into the radiometer digital camera system or downloaded to a computer for formatting or viewing.
Abstract: A device for temperature measurement uses an optical system to image the heat radiation emanating from a measurement spot on an object of measurement onto a detector. A sighting arrangement is also provided which has a diffractive optical system by which a light intensity distribution is produced which corresponds to the position and size of the measurement spot on the object of measurement.

Abstract: Passive infrared intrusion detector with means for determining the location of the fields of view covered by the system. In one disclosed embodiment, a small mirror is positioned near the sensing element and oriented so that a person looking at this mirror sees the fields of view through the optical system of the detector. A reference mark on the mirror appears in each of the fields seen by the person.
Abstract: Hand-held instrument for measuring the temperature of a target without contact with the target. The instrument utilizes a microprocessor and a digital display to calculate and indicate different temperature functions. Compensation is included for the effects of emissivity and ambient temperature changes which otherwise could result in inaccurate readings. Temperature trend direction liquid crystal arrow(s) actuated by the microprocessor are included in the display.
