METHOD AND APPARATUS FOR DISPLAYING THE TEMPERATURE OF AN OBJECT
First Claim
Patent Images
1. An infrared thermometer for projecting a temperature measurement onto an object being measured, the infrared thermometer comprising:
- an infrared thermopile with a field of view for determining a measured temperature of an object;
a light path including a visible light source, an aperture, and a dynamic display disposed between the visible light source and the aperture, wherein the dynamic display produces a pattern indicative of the measured temperature, the pattern including an optically transparent pattern and an optically opaque pattern wherein visible light from the light source travels through the optically transparent pattern to project a displayed image that is indicative of the measured temperature through the aperture; and
a display controller for controlling the dynamic display to alter the pattern to be indicative of the measured temperature.

5. A handheld infrared thermometer for projecting a temperature measurement onto an object being measured, the thermometer comprising:
-
an infrared thermopile with a field of view for determining a measured temperature of an object; a light path including a visible light source, an aperture, and a liquid crystal display disposed between the visible light source and the aperture, wherein the liquid crystal display produces a pattern indicative of the measured temperature, the pattern including an optically transparent pattern and an optically opaque pattern wherein visible light from the light source travels through the optically transparent pattern to project a displayed image that is indicative of the measured temperature through the aperture; and a display controller for controlling the liquid crystal display to alter the pattern to be indicative of the measured temperature. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A method for measuring the temperature of an object, the method comprising the steps of:
-
determining the measured temperature of a section of an object; generating on a display a pattern that is indicative of the measured temperature, the pattern including an optically transparent pattern and an optically opaque pattern; and projecting a displayed image that is indicative of the measured temperature onto the object by permitting visible light to travel from a light source through the optically transparent pattern to project the displayed image onto the object, wherein the displayed image is indicative of the measured temperature. - View Dependent Claims (13, 14, 15, 16, 17)
