摘要： A pixellated scintillator readout arrangement is presented, the arrangement comprising a plurality of scintillator pixels arranged in a scintillator array, and a plurality of photodetectors arranged to receive light from, or address, the scintillator pixels. The photodetectors may be arranged on both a first side and a second side of the scintillator array. Each photodetector may be arranged to leave a gap adjacent to the scintillator pixel which is addressed by that photodetector. Non-photosensitive elements such as tracking and bondpads may be arranged in at least some of the gaps. Electronic components such as electronic amplifiers may be arranged in at least some of the gaps. The photodetectors may be arranged in linear arrays addressing alternate lines of scintillator pixels on either side of the scintillator array. Each photodetector may be arranged to address a single pixel (as illustrated) or more than one pixel (not shown).

摘要： An optical detector (1) acts as a modular detection unit. It may for example be mounted on a separate micro-fluidic device (2) for detection of species within a channel (3) of the device (2). The detector (1) has mounting lugs (4) for mounting on the micro-fluidic device (2) for exact registry with the channel (3). A substrate (15) is folded over at a flexible part (25) through 180° and, at the top, supports a vertical emitting laser device (16). The lower branch of the substrate (15) supports an integrated circuit photo-diode array sensor (17) having chip bumps (18). The substrate (15) also supports emitter drive circuitry (26) and detector circuitry (27). The sensor (17) is a silicon integrated circuit, having an array of integrated photo-diodes (17(a)) in a silicon wafer (17(b)). There is a vertical through-hole (17(c)) in the wafer, to act as a guide for incident radiation emitted by the emitter (16) (arrows IR). Because of the single folded-over substrate arrangement the emitter 16 can be particularly easily and accurately aligned with the guide aperture 17(c).
