    Abstract: A spectrophotometer useful for measuring absorption or emission bands of a substance irradiated with optical radiation, comprises a light source for producing the optical radiation, a monochromator for isolating light of wavelength (W) from the optical radiation and which modulates the wavelength (W) by a predetermined wavelength amplitude (.delta.W), and a photodetector for detecting the intensity of light passing through the monochromator and for producing a measuring signal in response thereto. The monochromator operates under the control of an electronic control unit which produces a control signal that causes the monochromator to scan across a portion of the spectrum of the optical radiation at a frequency (f.sub.2) to transmit a narrow band of radiation at the wavelength (W). The control unit includes a modulation generator which produces a signal that causes the monochromator to modulate the wavelength (W) by the predetermined wavelength amplitude (.delta.W) at a frequency (f.sub.1). The spectrophotometer also includes an electronic evaluation unit which amplifies an a.c. component of the measuring signal that is attributable to the wavelength modulation in synchronization with the signal produced by the modulation generator. In one preferred embodiment, the monochromator comprises a diffraction grating and a drive unit which causes the diffraction to rotate about a pivot axis and which superimposes an oscillatory motion on the rotational movement. In another preferred embodiment, the monochromator comprises a Fabry-Perot resonator and a drive unit which adjusts the optical length of the Fabry-Perot resonator under the control of the control unit.

    Abstract: A respiratory CO.sub.2 detector (10) comprising an infrared lamp source (44) and an infrared detector (50) responsive thereto forming an optical path for detecting the change in CO.sub.2 concentration, or an obstruction in a cuvette (42). The output of the infrared detector (50) provides a high and low voltage signal to be applied to a feedback control loop (12) and to an output circuit (14).The feedback control loop (12) includes a peak detector (22), a contamination detector (24), a pulse-width modulator (26) and a low pass filter (28), the latter providing a DC bias on the infrared lamp (44). The peak detector (22) is connected to the pulse-width modulator (26) to maintain the lamp voltage constant and is connected to comparators (56,62) to compare both outputs of the peak and contamination detectors (22,24). The contamination detector (24) will respond to blockage in the cuvette (42).The output control circuit (14) includes a sample-and-hold circuit (30) and a subtractor (32) connected to the output of said infrared detector to receive the high and low voltage signal from the infrared detector, the outputs of which produce an output signal without the DC bias which is then inverted to provide a high quality waveform.

    Abstract: A device and method for measuring blood characteristics and parameters, especially arterial, venous, or differential blood oxygen saturation levels uses one or two probes containing a unique configuration of light emitters of two different wavelengths, and sensors which alternately illuminate and read reflected light from blood passing through a specially-designed cuvette. Electronic comparison of reflected radiation received by the probes produces a voltage which is linearly related to blood oxygen saturation level. An opto-electronic feedback network compensates for differences in blood optical density.
