Abstract: Various embodiments of an optical proximity sensor and corresponding circuits and methods for measuring small AC signal currents arising from the detection of pulsed AC light signals emitted by a light emitter and reflected from an object to detected in the presence of larger ambient light DC current signals are disclosed. Circuits and corresponding methods are described that improve the dynamic range, sensitivity and detection range of an optical proximity sensor by cancelling the contributions of DC current signals arising from ambient light signals that otherwise would dominate the detected small AC signal currents. The DC signal cancellation occurs in a differential amplifier circuit before small AC signal currents are provided to an analog-to-digital converter. The circuits and methods may be implemented using conventional CMOS design and manufacturing techniques and processes.

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 filer 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 translation: 误差检测器电路将对应于从光学拾取器的监视二极管提供的激光功率的值与表示目标激光功率的值进行比较，并将误差从目标值输出到转换开关。 切换开关选择用于CAV录制和CLV录制的低通滤波器之一。 用于CAV记录的低通滤波器具有比用于CLV记录的低通滤波器的时间常数更大的时间常数。 因此，在CAV记录期间，伺服环路的伺服增益因此设置为小于CLV记录期间伺服环路的伺服增益。 激光功率的变化变得温和。

Abstract: A temperature sensor that has a thermally conducting contact with a surface that emits electromagnetic radiation in proportion to the temperature of the contact is disclosed. The sensor has a resilient member attached to the contact and configured to extend the contact toward the object to be measured. A first light waveguide is attached to the contact and is configured to transmit the electromagnetic radiation from the contact. The sensor has a guide with a bore formed therein that the first waveguide is insertable into. When the contact is moved, the first waveguide moves within the bore. A second waveguide is attached to the guide such that a variable gap is formed between the ends of the first waveguide and the second waveguide. Electromagnetic energy from the first waveguide traverses the gap and can be transmitted by the second waveguide. The guide allows the first waveguide to move with the contact in order to ensure that the contact is fully engaged with the surface of the object.

Abstract: L'invention concerne les écrans d'entrée de tubes intensificateurs d'image radiologiques. L'écran d'entrée comporte un scintillateur (12) déposé sur un substrat d'aluminium (10); il convertit des photons X incidents en photons visibles qui viennent ensuite exciter une photocathode (16). Des photons lumineux produits par le scintillateur sont émis vers l'arrière et réfléchis par la couche d'aluminium; mais cette réflexion réduit la résolution. Selon l'invention, pour supprimer cette réflexion, on propose de réaliser un écran d'entrée dans lequel on interpose entre le substrat et le scintillateur une couche mince (20) transparente ou peu absorbante (aux longueurs d'onde émises par le scintillateur) calculée pour provoquer un effet anti-reflet. Comme couche peu absorbante anti-reflets on choisira de préférence de l'oxyde d'indium, ou encore de l'oxyde d'antimoine, d'étain ou de bismuth, ou encore une combinaison de ces oxydes, telle que de l'oxyde d'indium-étain. L'épaisseur est de quelques centaines à quelques milliers d'angstroems.
