Abstract: A bolometer-type infrared sensor using a resistor with a hysteresis in its thermal characteristic of resistance increases the sensitivity. A first temperature controller raises or drops the temperature of the diaphragm from its outside. A second temperature controller raises the temperature of the diaphragm from its inside by supplying electricity to the bolometer film. The first temperature controller defines a lower-side temperature of a temperature cycle while the first and second temperature controllers define an upper-side temperature thereof. The temperature of the diaphragm is controlled according to the temperature cycle. A signal on the diaphragm is read out at the upper-side temperature.

Abstract: The present invention discloses a probe assembly for used in an infrared ear thermometer. Given that the exchanged thermal radiation and the infrared detector's temperature are known, the subject temperature can be calculated according to Stefan-Boltzman's law. To make the Stefan-Boltzman's law applicable in a dynamic environment where temperature may vary greatly, the contact temperature sensor (thermistor) must acuurately and fast track the temperature of the infrared detector (thermopile sensor). By using the heat transfer theorem, the disclosed assembly makes the thermistor accurately track the cold junction temperature of the thermopile chip without being in an isothermal condition. Not only minimizes the measurement error in a dynamic environment, the design of the disclosed probe assembly also makes a samll and compact infrared thermometer possible.

Abstract: An anti-reflective structure is formed on a surface to transmit incident light with minimal losses. The anti-reflective surface has a plurality of protrusions having a feature size smaller than the wavelength of incident light. The protrusions increase in height in either a sloped linear manner or in a curvilinear manner, and the protrusions repeat across the surface in at least one dimension to transmit the incident light. Gray scale lithography may be used to produce these patterns of protrusions in photoresist layers. High fidelity transfer of the protrusion patterns into the surfaces is accomplished by utilizing, for example, an electron cyclotron resonance plasma. Transmission values at such patterned surfaces maybe as high as 99.3%.
