摘要： An optical scanning system uses a low-resolution scanning operation, to automatically adjust the sensitivity of the system. The system performs a low-resolution scanning operation by scanning a line, automatically and iteratively setting the levels of excitation signal power and detector gain, skipping a plurality of lines and scanning a next line, adjusting the levels as appropriate, skipping a plurality of lines and scanning a next line, and so forth. After the system sensitivities have been set, the calibrated system then scans all the lines of the sample to collect data. The calibrated system thus scans for the first time the lines that were skipped during the low resolution scanning operation.

摘要： A system including confocal and triangulation-based scanners provides dimensional information about microscopic targets. The targets are illuminated with a scanning beam of electromagnetic radiation such as laser light. A confocal detector is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem includes a detector placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors. In this way, triangulation-based data is acquired in parallel or sequentially with at least one slice of confocal image data, there being sustantially perfect temporal and spatial registration between the two data channels.

摘要： A system including confocal and triangulation-based scanners or subsystems provides data which is both acquired and processed under the control of a control algorithm to obtain information such as dimensional information about microscopic targets which may be "non-cooperative". The "non-cooperative" targets are illuminated with a scanning beam of electromagnetic radiation such as laser light incident from a first direction. A confocal detector of the electromagnetic radiation is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam of electromagnetic radiation. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem also includes a detector of electromagnetic radiation which is placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors. In this way, data from at least one triangulationbased channel is acquired in parallel or sequentially with at least one slice of confocal sensor data having substantially perfect temporal and spatial registration with the triangulation-based sensor data. This allows for fusion or further processing of the data for use with a predetermined measurement algorithm to thereby obtain information about the targets.

摘要： A method and system are provided for flipping a tray of parts such as integrated circuit packages including a pair of flippable storage trays. A first storage tray has an upper surface which forms a grid of storage compartments wherein each of the storage compartments is adapted to hold a single integrated circuit package. Initially, the first tray is received at a flip station from a first part processing station. Then, the first and second trays are joined together so that they mate. Then, the mated first and second trays are inverted so that the packages are held in the second tray. Then, the first and second trays are separated and the second tray which now holds the plurality of packages is transferred to a second part processing station. Then, the cycle is repeated with a third tray of parts and the now empty first tray.

摘要： A variable capacitance high precision, stable transducer for detecting position of a moving member including a first stationary conducting surface connected to a source, a second surface with at least two conducting, sensing regions and a third movable conductive surface located between the first surface and the second surface and connected to the moving member. The third surface is adapted to modulate charge transfered from the source surface before reaching the sensing regions. The difference of signals detected at the individual sensing regions is utilized to determine the position of the moving member and the sum of the signals is utilized to achieve appropriate correction in a feedback loop connected to the source.

摘要： An analog optical position transducer for detecting angular position of a rotatable member of a motor. The transducer includes a plurality of sensing surfaces placed in one frame of reference and a modulator located in another frame of reference, one of the frames of reference being stationary and the other moving with the rotatable member. The relative angular position of the two frames of reference is determined from the amount of light varied by the modulator and detected by the sensing surfaces. The modulator employs a radiation source which is located on a diffusive surface or which irradiates the diffusive surface of the modulator. Radiation emitted from the diffusive surface is modulated by the modulator depending on the relative position of the modulator and the sensing surfaces. A lens focuses the emitted radiation onto the sensing surfaces. The sensing surfaces are symmetrically arranged about an axis passing through the center of rotation of the rotor, and their relative distribution with respect to the surfaces of the modulator enables differential detection. An analog circuit connected to the sensing surfaces continuously determines the angular position of the rotatable member from the amount of light detected at each of the sensing surfaces. The system is effective to accurately position a mirror in a high speed laser scanner.
