“…Compared with other BDJ-based systems [112][113][114], this system includes an irradiance detection pathway that can be used in combination with the color information to provide color change -intensity change disambiguation (CCICD). The irradiance detection pathway is based on the work by Delbruck and Mead [23] with a single standard CMOS photodiode (see Figure 21).…”

“…The device features two photodiodes in stacked form, and has a superimposed spectral response covering visible and near-IR ranges [6]. It can thus be operated for photodetection like a photodiode, with more sensitive response thanks to signal contributions of the two photodiodes.…”

We have designed a cost-effective, fiber optic bundle-based detection system for microarray fluorescence measurements. A bundle, fabricated with thin-cladding fibers of 50-µm in core diameter, is used for spot excitation and collection. The collected optical signal is detected by a CMOS BDJ (Buried Double p-n Junction) detector, which can be operated either as a photodiode or as a wavelength-sensitive device. For improving measuring rate of a microarray, we have proposed a direct spot scanning technique, which is based on a prior knowledge about the predefined microarray's mask pattern, and operates to bring the bundle successively over each spot for single-point measurement. It is implemented with a microarray registration procedure to determine the spots' positions. The detection system with implemented scanning technique has been tested using microarray samples. Its scanning operation has been verified by comparing the determined spots' coordinates to the microarray image.
