An optical detector with appropriate electronics and readout. Photomultiplier tubes supply good sensitivity for wavelengths in the visible range, and Ge, Si, or other photodiodes can be used in the near infrared range. Multichannel detectors like CCD or photodiode arrays can reduce measurement times, and a streak camera or nonlinear optical techniques can be used to record ps or sub-ps transients.

The ideal high-throughput analytical technique would be efficient in terms of required resources and would be scalable to accommodate an arbitrarily large number of samples. In addition, this scalability would be such that the dependence of the cost of the equipment to perform the experiments would scale in a less than linear manner as a function of the number of samples that could be studied. The only way to accomplish this is to have one or more aspects of the experimental setup utilize an array-based approach. Array detectors are massively multiplexed versions of single-element detectors composed of a rectangular grid of small detectors. The most commonly encountered examples are CCD cameras, which are used to acquire ultraviolet, visible and near-infrared (IR) photons in a parallel manner. Other examples include IR focal plane arrays (FPAs) for the collection of IR photons and channel electron multipliers for the collection of electrons.

Night-vision systems have already been introduced in very low volumes in some upscale automobiles. Their function is based on either infrared-sensitive array detectors or a CMOS camera combined with active near-infrared illumination of the scene. The night vision approach further completes the idea of a sensitive car . 

A variety of commercial diode array detectors are available which cover the wavelength range from 200 to over 1000 nm (see Table I for representative examples). However, for work in the red and in particular the near-infrared spectral range, the number of available dedicated detec-...
