摘要:
A radiometer includes a sighting system that generates a digital image of an object surface having an area that is to be imaged onto the IR detector. A shape outline is overlaid on the digital image of an object surface to indicate the extent of the energy zone that is imaged onto the IR detector. In one embodiment, a shape is displayed between the locations of two imaged skewed laser dots to indicate the extent of the energy zone without requiring a range determination.

摘要:
An improved ratio type infrared thermometer utilizes integrating amplifiers for each waveband having the integration time automatically set so that the output voltage utilizes the full range of an analog to digital convertor. The gain and offset of the amplifiers is not ambient temperature dependent so accurate digital representations of the signal for each waveband are provided. The linearized output of each detector is optionally provided so that special or proprietary algorithms for computing the temperature of colored objects can be utilized. A special feature for downloading of updated new programs utilizes a "programming jumper" and an attenuation warning signal is provided for selected levels of attenuation.

摘要:
A graphical user interface for configuring parameters associated with a portable infrared imager is provided. The interface can be used to manually or automatically set range and span parameters. The interface can also be used to configure one or more alarms to notify a user that a detected temperature is outside a predetermined range. In some embodiments, a non-linear temperature scale can be displayed.

摘要:
A pyrometer for measuring the electromagnetic radiation emitted by an object comprises a first detector to which the radiation is delivered through an optical system as well as a second detector to which the radiation emanating from a reference element is delivered through the same optical system. The temperature of the reference element is monitored and a rotary optical modulator periodically enables and disables the delivery of radiation to the detectors. The output signals from the two detectors are processed to determine the difference therebetween. The sensed temperature of the reference element is taken into account as a part of determining the difference between the two detector output signals. In this way it is possible for the characteristic radiation of the optical system largely to be suppressed. The optical modulator comprises a semi-circular disk having a polyethylene terephthalate substrate coated on each side with metal. The disk is rotated through 180.degree. increments by a stepping motor such that, in one angular position, the disk permits reception by the two detectors of radiation from the optical system and, in the other angular position, the disk prevents reception by the detectors of radiation from the optical system.

A graphical user interface for analyzing thermal images is provided. The interface can be used to identify the temperatures at multiple areas of interest defined on an image. The areas can be denoted by configurable markers of different predetermined shapes. In some embodiments, the interface simultaneously displays temperature statistics relating to the user-identified areas of interest.
