    Abstract: A miniature, flexible, fiber-optic scanning endoscope for nonlinear optical imaging and spectroscopy. The endoscope uses a tubular piezoelectric actuator for activating a cantilevered optical fiber from which pulsed light produced by a laser source exits and is directed to a target region through a micro-lens. The actuator is activated by two modulated signals that achieve two-dimensional beam scanning in a desired scan pattern. A double-clad optical fiber is employed for delivery of the excitation pulsed light and collection of emitted light received from the target region. The pulsed light travels through a core of the double-clad optical fiber, and the emitted light from the target region is directed into the core and inner cladding of the optical fiber and conveyed to a proximal end, for detection and processing. The emitted light can include multiphoton fluorescence, second harmonic generation light, and spectroscopic information, for imaging.

    Abstract: A spectrophotometer has a first photodetector (24) and a second photodetector (25) which is displaced spatially from the first photodetector in the direction of increasing wavelength in the spectrum. At any given time the second photodetector receives light at a wavelength which is substantially greater than that being received simultaneously by the first photodetector at that time. The first photodetector has a first range of wavelengths over which it is operable and a first upper operating limit, and the second photodetector has a second range of wavelengths over which it is operable and a second upper operating limit, the second range overlapping the first range and the second upper operating limit being greater than the first upper operating limit. Thus the range of operation is extended, and data in two different ranges is processed simultaneously. The spectrophotometer comprises a housing (1) containing a light source (11), a monochromator (15, 16, 18) and the photodetectors, there being a fibre optic connected to a probe (2) for transmitting light from the light source to a sample to be analysed and receiving light from the sample. Optical components are mounted to a chassis (26) of the housing rigidly, the chassis being connected to the housing by shock absorbing mounts (28, 29). The light source is mounted to the housing by means of an adjuster (24) providing for adjustment laterally with respect to the optical axis of the light source.

    Abstract: An embedded data acquisition and control system for precision instruments is disclosed. It provides a synchronization of stepper motor position and analog-to-digital converter, in order to minimize the wavelength shift error due to the asynchronous. The controller synchronizes the event of reading the A/D converters with each stepper motor position. According to another future of the invention, a position encoder is coupled to the stepper motor shaft for archiving in an actual position feedback. Because the embedded controller has the position feedback, it can initiate the next step command as soon as the position feedback reaches its target. The step rate is increased by reducing the time delay that was set by conservative value as indicated in the open loop control mode. A further future of the invention provides optical isolation to minimize motor noise.

    Abstract: A fluorescence spectrophotometer having an excitation double monochromator (104), a coaxial excitation/emission light transfer module (106), and an emission double monochromator (110). Each monochromator includes a pair of holographic concave gratings (203, 210) mounted to precisely select a desired band of wavelengths from incoming broadband light without using other optical elements, such as mirrors. Selected excitation light is directed into a sample well (108) by a light transfer module (106) that includes a coaxial excitation mirror (302) positioned to directed excitation light directly to the bottom of a well (108) of a multi-well plate. Fluorescence emission light that exits the well opening is collected by a relatively large coaxial emission mirror (304). The collected emission light is wavelength selected by the emission double monochromator (110). Selected emission light is detected by a photodetector module (112).
