    摘要: A system and method for multimode imaging of at least one sample is disclosed. The system includes at least one light source; an optical system selected responsive to a mode of operation of the imaging system; and a detector capable of selective reading of pixels. The at least one sample is moved elative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving. The method includes the steps of (1) selecting a mode of operation for the imaging system; (2) transmitting light from at least one light source through an optical system selected in response to the mode of operation for the imaging system; (3) moving the at least one sample relative to the optical system using a sample movement technique selected from the group consisting of step sample moving and continuous sample moving; and (4) selectively reading pixels with a detector.

    摘要: The present invention relates to an apparatus and method for imaging time resolved fluorescence in biochemical and medical samples. In a primary aspect, the device includes a lens of large aperture, a flash lamp in the illumination path, a fast-acting solid state shutter or a gated detector in the emission path, a device for delivering homogenous monochromatic illumination to a plurality of wells distributed within a microwell plate, a digital camera of high quantum efficiency, and a computer under computer control, the lamp is pulsed at short intervals. The fast-acting emission shutter or gated detector operates to limit exposure of the camera to a period some microseconds after the extinction of each lamp pulse, during which only delayed fluorescence is transmitted to the camera. The invention achieves simultaneous time resolved imaging of a plurality of samples, with high sensitivity and high throughput.
