    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.

    Abstract: An error detector circuit compares a value corresponding to a laser power supplied from a monitor diode of an optical pickup with a value representative of a target laser power, and outputs an error from the target value to a change-over switch. The change-over switch selects one of low-pass filters used for CAV recording and CLV recording. The low-pass filter used for CAV recording has a larger time constant than that of the low-pass filter used for CLV recording. The servo gain of a servo loop during the CAV recording is therefore set smaller than that of a servo loop during the CLV recording. A change in the laser power becomes gentle.

    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.
