摘要:
A detector comprises a plurality of photoelectric converters to output an electrical signal corresponding to an incident light, and a plurality of filter circuits provided corresponding to each of the plurality of photoelectric converters or to each of a plurality of element groups respectively including a predetermined number of the photoelectric converters of the plurality of photoelectric converters, the plurality of filter circuits attenuating a signal having a predetermined frequency from the electrical signal output from the plurality of photoelectric converters. In the above-described detector, the plurality of photoelectric converters may be provided in a first substrate, and the plurality of filter circuits may be provided in a second substrate laminated on the first substrate.
摘要:
Provided is a light detecting apparatus including: a first photoelectric converting unit which outputs a first electrical signal in accordance with an incident light including a modulated light component and a background light component; a filter unit which outputs a second electrical signal resulting from the modulated light component being reduced in the incident light; and a signal processing unit which subtracts the second electrical signal from the first electrical signal to reduce a component corresponding to the background light component in the first electrical signal. In the light detecting apparatus described above, the photoelectric converting unit may include a first photoelectric converting element and a second photoelectric converting element each of which outputs the first electrical signal, the filter unit may attenuate the signal corresponding to the modulated light component in the first electrical signal output from the second photoelectric converting element, and the signal processing unit may subtract the second electrical signal from the first electrical signal output from the first photoelectric converting element.
摘要:
Misalignment of substrates may occur even though the substrates are precisely aligned together due to the factors after the alignment. A substrate bonding apparatus for bonding a first substrate and a second substrate together comprises an aligning section which aligns the first substrate and the second substrate together in an aligning apparatus; a carrying section that carries out the first substrate and the second substrate from an aligning section that have been aligned; a bonding section that bonds the first substrate and the second substrate together that have been carried by the carrying section; a judging section that judges whether there is misalignment of the first substrate and the second substrate prior to being carried by the carrying section, after alignment in the aligning section.
