Time Resolved Spectroscopy of Protein Crystals
Time Resolved Spectroscopy of Protein Crystals Customer Case The customer is involved in Time Resolved Spectroscopy of protein crystals. This involves shooting a laser onto the protein crystals and measuring the pulses generated by the crystals (as they are projected out of the sample) and their decay over time. Due to the very noisy nature of the return signals, it is essential to average many pulses in order to recover the pulse shape and measure the decay. The decay takes place over many tens of milliseconds, so it is necessary to acquire very long records (in the order of [...]

White Paper: Electrical Safety & Compliance Testing for Appliance & Consumer Product Manufacturers
Introduction Electrical appliances, computers and peripherals, power tools and other devices found in the home and office environments must be tested to confirm adherence to a plethora of stringent certification standards. The vast array of consumer devices for the home and office — from blenders and ovens to computers and high-definition LED TVs — are becoming increasingly sophisticated. Refrigerators, once basic electrical appliances, now often include adjustable speed motor controls, digital displays and Bluetooth communications. While the complexity and functionality found in this class of devices varies extensively, there is one thing they all have in common when [...]
Hyper Remote Laser Sensor
Hyper Remote Laser Sensor Customer Case The customer is at the prototype stage for building a hyper remote sensor which will fly over the ocean and be able to see 100 to 200 feet below the surface. The sensor is being designed in order to determine the composition of the ocean and the ocean floor. This remote sensor will be extremely useful in the detection of pollution and studying the way pollution is being distributed by ocean currents. It will also be useful to the military (navy) for creating mine-finding systems. A deep blue laser will be used to [...]
Laser Induced Fluorescence (LIF)
Laser Induced Fluorescence (LIF) Customer Case A customer has developed a breakthrough technique for the application of laser-induced fluorescence (LIF) detection to high performance liquid chromatography, capillary e lectrophoresis, sequencing and microbial analysis. The technique involves using fluorescence decay curves at multiple wavelengths simultaneously, leading to true 3-D fluorescence spectroscopy (i.e., fluorescence intensity as a function of wavelength and delay time relative to pulsed excitation). They have a requirement to increase the laser pulse repetition frequency (PRF) from 20-50 pulses per second to 500-1000 pulses per second. Basically, they want to collect and time resolve the fluorescence signal for [...]

Optical Spectroscopy
Optical Spectroscopy Customer Case A customer who is completing his doctorate in Chemistry at the California Institute of Technology has identified the need to measure fast optical signals using fast photo-detectors. The signal pulse width is as short as 2ns. Signals will be acquired at a 1KHz repetition rate, with a record length of 1,000 to 10,000 data points. GaGe Case Solution The CompuScope 82G, an 8-bit, 2GS/s A/D and Scope card for PCI Bus, is the best solution for this customer. With relatively small record sets, the customer is able to keep up with the 1KHz Pulse Repeat [...]

EV Batteries Need Thickness Gauging for Lower Costs and Higher Performance
EV batteries need to cost less and last longer. Until the e-mobility industry solves these challenges, electric vehicle (EV) adoption won’t match the hype that’s driven by Tesla, the established automakers, and a host of startups who are attracting investors. According to Axios, the expense of owning an electric vehicle will exceed that of owning a conventional one until EV batteries cost less than $100/KWh to produce. Unfortunately, the EV industry isn’t expected to hit that target for another ten years. Yet, there is some encouraging news. Less expensive and better performing EV batteries are just a few years [...]
Kinetics of Protein Dynamics
Kinetics of Preotein Dynamics Customer Case The customer is measuring kinetics of protein dynamics with a time scale of between a few nanoseconds and about a hundred milliseconds. The customer's two response signals occur after a few-nanosecond-pulse excitation that repeats at a rate of 1-10Hz. This requires a bandwidth from DC to a few hundred MHz, sampling speed of about 1-2GS/s, and processing time for one acquisition that is less than 1-0.1secs. An analog signal of about 10-30mV comes from a Photo-Multiplier Tube (PMT) or a photo-diode with a trans-impedance pre-amplifier. The customer is currently using a couple of [...]

Transducer Selection for High Resolution Applications
High resolution applications do not always require an interferometer. If you want to make accurate measurements in the micron to picometer range, then an MTI Digital Accumeasure D100 HD or D200 system may be what you need. Laser interferometers can sell for more than $15,000 and be difficult to setup. For example, you may have to buy additional optics to guarantee a good return signal since the laser beam must reflect off a mirror surface or precision retro reflector in order for the beam to re-enter the interferometer’s optics at less than a degree of reflection angle. The downsides [...]
Radioactive Nuclear-Decay Detection
Radioactive Nuclear-Decay Detection Customer Case The customer has a requirement for PC-based waveform digitizer cards to digitize shaped pulses derived from nuclear-decay detectors. These pulses vary in their rate (frequency of occurrence) and amplitude. Their shape is approximately Gaussian with a full-width at half the maximum amplitude (FWHM) of 3-5 microseconds. The characterization of each pulse is critical for the accurate and precise determination of the activity of radioactive materials. These materials have very low count-rates (0.02 pulses per minute) to relatively high count-rates (>1000 pulses per minute). Important to the measurement process are the speed and reliability of [...]
