![]() The central requirement for sensing and imaging of such events in real time is the temporal resolution shorter than the time scale of changes in the dynamical process. Applications that require high scan rates (typically ∼1 kHz or higher in 2D) include identification of missiles and aircrafts via light detection and ranging (LIDAR) 1, 2, 3, 8, 9, 12, 13, non-destructive inspection of acoustic instruments 10, structural dynamics 10, 12 and microelectromechanical systems (MEMS) 11, 12 via laser-scanning surface vibrometry 1, 11, 12 and observation of biomechanical motility 4, cellular network dynamics 5 and neural activity 6, 7 via laser-scanning confocal and multi-photon microscopy 1, 3, 6, 7. Here low scan rates result in motion blur and failure to capture fast transient information. For sensing and imaging methods based on laser scanners 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, the ability to scan at high speeds is crucial for multi-dimensional evaluation of moving objects and dynamical processes. Laser scanning technology is one of the most integral parts of today's scientific research 1, 2, 3, 4, 5, 6, 7, 8, manufacturing 1, 2, 3, 9, 10, 11, 12, 13, defense 1, 2, 9, 10, 13 and biomedicine 1, 4, 5, 6, 7, 14, 15, 16. To show our scanner's broad utility, we use it to demonstrate unique and previously difficult-to-achieve capabilities in imaging, surface vibrometry and flow cytometry at a record 2D raster scan rate of more than 100 kHz with 27,000 resolvable points. This method employs spatial dispersion of temporally stretched broadband optical pulses onto the target, enabling inertia-free laser scans at unprecedented scan rates of nearly 100 MHz at 800 nm. Here we present a new type of laser scanner that offers ∼1,000 times higher scan rates than conventional state-of-the-art scanners. Unfortunately, conventional laser scanners are often too slow, resulting in limited precision and utility. In many applications, high-speed scanning capability is essential for scanning a large area in a short time and multi-dimensional sensing of moving objects and dynamical processes with fine temporal resolution.

Several modulation modes are also available (gate, burst and scan modes) that can be triggered by internal or external sources. Other features are available, such as pulse generation with a 100ps wide resolution with a 30ps lower jitter and variable rise and fall times. Software for editing and generating arbitrary waveforms, running on a PC, is supplied with the instrument. These instruments can generate various standard waveforms as well as custom signals at sampling rates up to 800 MS/s. They are also distinguished by their phase control capability to within 0.001 degrees. These generators are equipped with two channels which can operate in independent, coupled or tracking mode. Both standard signal and arbitrary waveform generators in the TGF3000 range can deliver signals up to frequencies of 80 and 160 MHz. ![]() RS Components (RS), the brand of Electrocomponents, distributor of electronic components, industrial equipment and test and measurement instruments, announces the availability in its catalogue of two arbitrary function and signal generators from the TGF3000 range of Aim-TTi (Thurlby Thandar Instruments) with which RS has been a partner for 40 years. ![]()
