Abstract: A temperature sensor utilizing optical temperature measuring techniques is constructed to make firm contact with a surface whose temperature is being measured, an example application being the monitoring of semiconductor wafers or flat panel displays while being processed. A cap is mounted near but spaced apart from an end of a lightwave guide, with a resilient element that applies force of the cap against a surface whose temperature is being measured as the cap is urged toward the optical fiber end. An optical temperature sensing element, such as luminescent material or a surface of known emissivity, is carried within the cap. A bellows with a closed end conveniently serves as both the cap and the resilient element. An alternative temperature measuring device installs an optical temperature sensing material within a test substrate behind an optical window, and then views the sensing material through the window.

Abstract: An image pickup apparatus capable of reducing influence of flicker while suppressing delay of start of photographing. An image pickup device and a photometric sensor pick up images of an object. A CPU obtains images by controlling driving of one of the device and the sensor to perform charge accumulation and charge readout. Further, the CPU detects a flicker frequency and a flicker phase of a flicker light source, and stores them in a memory as first information. When photographing, if the CPU determines that the first information is not valid, an ICPU obtains images by controlling driving of the other of them to perform charge accumulation and charge readout. Further, the ICPU detects the flicker frequency and the flicker phase and stores them in a memory as second information. The CPU controls exposure timing according to the second information to perform photographing.

Abstract: A brightness time change of the target object is analyzed and a periodic brightness change is extracted. By the matching with a database which includes data of a candidate of the target object, the features of the target object are estimated. If even the brightness data can be acquired even if the resolution of the optical observation is low, the features and states of the target object can be estimated.

Abstract: Provided is a test apparatus that tests a device under test including an optical coupler transmitting optical signals in a direction perpendicular to a device surface. The test apparatus includes a substrate on which the device under test is to be loaded, an optical transmission path that transmits the optical signals, and a lens section facing the optical coupler on the substrate that focuses the optical signals from an end of either the optical coupler or the optical transmission path to an end of the other.

Abstract: An image reading device has: a light source at which plural light-emitting elements are arrayed; a detection unit that detects light amounts of illumination light which are emitted from the light-emitting elements and are reflected by a reference plate; a derivation unit; and an adjustment unit. On the basis of detected light amounts, the derivation unit derives difference amounts between a reference value and average values of light amounts per predetermined first number of adjacent light-emitting elements. On the basis of the derived difference amounts, the adjustment unit adjusts light amounts per the first number of light-emitting elements such that the average values become the reference value.
