    摘要： A monolithic optical detector for determining spectral content of an incident light includes at least a first and second well in a substrate, the second well formed proximate the first well. The first well is configured to be exposed to incident light and for generating a first photocurrent as a function of the incident light. The second well is configured to be shielded from the incident light and for generating a second photocurrent as a function of the incident light. Lastly, a processing and control unit, responsive to the first and second photocurrents, determines an indication of spectral content of the incident light. A method and device parameter controller are also disclosed.

    摘要： A monolithic light-to-digital signal converter (1.10) includes a photodiode array (1.24) having a plurality of sections with each section producing a current signal in response to incident light, a current-to-digital signal converter circuit (1.28) for converting selected ones of the current signals to a digital signal, and a control circuit (1.26) for scaling the digital signal in response to user supplied programming signals. The control circuit (1.26) also responds to user supplied programming signals to supply control signals to current-to-digital signal converter circuit (1.28). Current-to-digital signal converter circuit (1.28) is responsive to the control signals for combining selected ones of the current signals into a composite current signal and converting the composite current signal to a digital signal.

    摘要： A photosensor device (41) having tapered photodiodes (53, 55) that are interdigitated and which is compatible with typical ASIC, CMOS and BiCMOS processes. A left side photodiode array of tapered regions (53) of a first conductivity type is disposed into an epitaxil layer of a second conductivity type. This array of photodiodes is coupled together and further coupled to a first output terminal (43). A right side photodiode array of tapered regions (55) of said first conductivity type is disposed into the epitaxial layer of the second conductivity type, spaced apart from the left side photodiode by a minimum distance. A second output terminal is coupled to the array of right side photodiodes (51). An incident light spot (39) is focused onto the sensor. The amount of current generated at the first and second output terminals (43, 51) will be proportional to the area of the left photodiode array and the area of the right photodiode array which is receiving light. By comparing the current generated at the first and second output terminals, the position of the incident light spot can be accurately measured as a percentage of the total width of the sensor. The photosensor (41) may be used in many applications but is particularly well suited to autofocusing systems. Several embodiments are described which vary the size and number of photodiodes used. An integrated circuit (123) which incorporates the photosensor with the circuitry needed to output a digital position measurement is described.

    摘要： Defective pixels in a CMOS array give rise to spot noise that diminishes the integrity of the resulting image. Because CMOS arrays and digital logic can be fabricated on the same integrated circuit using the same processing technology and relatively inexpensive and fast circuit can be employed to digitally filter the pixel data stream and to identify pixels having values that do not fall in the range defined by the immediately neighboring pixels and the deviate from the neighboring pixels by more than a threshold amount. Such conditions would indicate that the deviation is caused by a defective pixel rather than by desired image data. The threshold amount can be preprogrammed or can be provided by a user or can be dynamically set using feedback indicating image quality. The filter would also provide a solution for other sensors such as CCD, although a single chip solution would likely not be possible.

    摘要： A simple low-cost fiber optic connector having a body member into which a ferrule is inserted and held in place by an expandable retainer which allows the ferrule to snap out of the assembly upon the application of a substantial pulling force, and thereby avoid damage to the fiber or to the connector. A preferred embodiment includes two aligned ferrules inserted into opposite sides of the body such that their tips meet at the center to interconnect the ends of two optical fibers. A multiple-ferrule embodiment is also contemplated.
