Abstract：
:An opto-electronic system has been developed to measure movements of insect appendages. It is made from a mirror-lens and a linear position-sensitive photodiode. The design of the mirror-lens has been exploited to axially mount a high intensity halogen light source in front of the mirror-lens. The system monitors a reflective marker which is attached to the moving object. Upon illumination by the light source the reflected light is picked up by the optical system and is focussed on the diode. The diode provides a voltage output proportional to the distribution of the light on it's surface. Since the marker is the brightest spot in the image the output of the system corresponds to the position of the marker. At a working distance of 80 cm appendage movements with amplitudes from 10 microm to 20 mm peak-peak amplitude can be recorded. The system accurately detects movements ranging from slow positional changes to 5 kHz oscillations. Currently it used to measure the stridulatory wing movements of crickets but may be applied to a variety of movement recordings.
