Measurement of curvature and profile of a reflective test surface by simultaneous measurement of slope at two closely spaced points on the test surface. A pair of parallel, nearly collimated light beams, which are slightly displaced relative to each other and of opposite linear polarization, and which intersect the test surface are reflected by the test surface, separated by a polarizing beam splitter and focused onto individual position sensitive detectors, which sense the slopes of the test surface at the points where it is intersected by the beams. The difference between the measured slopes is proportional to the local curvature. The device can be scanned along the surface to give a profile of measured curvature values, which are twice integrated to give the surface profile, although measurement at a single point without any such processing yields the test piece curvature. The device is reconfigured to test surfaces with different curvatures by virtue of one of the detectors being movable during initial alignment, and by virtue of a steering mirror and associated servo control system which maintain an essentially constant angle of incidence on the test surface.

Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument for biological or chemical analyses. The pulsed laser may produce sub-100-ps optical pulses at a repetition rate commensurate with electronic data-acquisition rates. The optical pulses may excite samples in reaction chambers of the instrument, and be used to generate a reference clock for operating signal-acquisition and signal-processing electronics of the instrument.

Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument. The mode-locked laser can produce sub-50-ps optical pulses at a repetition rates between 200 MHz and 50 MHz, rates suitable for massively parallel data-acquisition. The optical pulses can be used to generate a reference clock signal for synchronizing data-acquisition and signal-processing electronics of the portable instrument.
