Abstract: A hand-held, battery operated, single photon sensitivity phytoluminometer is claimed for rapid, simple nondestructive, noninvasive evaluation of photosynthetic topography in green leaves. All the steps for generating phytoluminescence are performed within a single, light tight enclosure. The sensitivity of the instrument is such that stress induced changes in photosynthesis can be detected seconds after occurrence. Thus phytoluminography is made an easily applied technique for practical use by all those concerned with plant life.

Abstract: A wavelength monitor/stabilizer for narrowly controlling the bandwidth of laser; the monitor/stabilizer uses parameters Q, F or G derived by measuring diameters of interference fringes given by the beam of the wavelength-controlled narrow bandwidth laser e.g. excimer laser and those given by the reference light e.g. of a mercury lamp. The controlling is made by controlling the parameter to be in a predetermined range. An image sensing unit for detecting the interference fringes are splitted into plural image sensors with adjustable distance for enabling more rapid measurement by skipping the in-between part.

Abstract: A spectrometer apparatus uses a spectrum resolving sensor containing an opto-electronic monolithic array of photosensitive elements, each preferably sub-millimeter in size and pitch, and a continuous variable optical filter, that is permanently aligned with the array. Polychromatic light passing through the variable filter is spectrally resolved in accordance with the local filter transmission function, and is incident upon the photosensitive elements in the array. The electrical output of each element in the array is thence a function of the local transmission function of the variable filter and the output of all the elements provides the spectral contents of the polychromatic light. High spectral resolving power is obtained by subtraction of the output signal of adjacent elements in the array.
