Angle Measurement And Monitoring
Angle Measurement And Monitoring Industrial Angle measurement and monitoring Robot Guide Introduction What do sheet metal, speakers, and wine bottles all have in common? They all require precise angle measurement to ensure product consistency and quality. Whether you're working in metal fabrication or consumer product packaging, an angle measurement sensor is essential for measuring critical angles and profiles with high precision. Precision Angle Measurement in Sheet Metal Press Brake Applications Many industrial applications, especially in sheet metal fabrication, rely on angle measurement sensors to monitor and control bends. For example, in [...]
Piezoelectric Stack Motion
Piezoelectric Stack Motion Research & Development Piezoelectric Stack Motion Displacement Description Fotonic sensors are ideal for making dynamic measurement of very small oscillatory motions. Using the MTI-2100 with a spectrum analyzer, angstrom level measurements are possible. Would you like to know more? Okay let’s set up some basic equipment and get started. Piezoelectric crystals expand and contract when voltage is applied across the stack. By controlling the amplitude of the applied signal we control the magnitude of the displacement. The test setup A Spectrum Analyzer A Signal Generator to drive piezo device [...]
Thickness and TTV of Semiconducting Wafers
Thickness and TTV of Semiconducting Wafers Semiconductor Thickness And TTV Of Semiconducting Wafers Thickness Description Introduction:  Silicon wafers are ordinarily highly conductive and easy to measure with standard capacitive displacement sensors (See MTI’s Proforma 300i). Measuring the thickness of GaAs wafers that have high bulk resistivity (>10k Ohm/cm) is a little more difficult because the wafers act as non-conductive insulators in a capacitive sensors measuring field. Fortunately, MTI has a solution to this problem. Solution:  It’s possible to measure the thickness and TTV of high resistivity semiconducting wafers (like GaAs) [...]
Pulsed Electric Field Food Processing
Pulsed Electric Field Food Processing Customer Case Pulsed Electric Field Food Processing is a continuous food processing system in which beverages (with a known conductivity) are pumped through a chamber containing an electrode. Pulses of high voltage electricity are passed across the electrode, thus through the liquid as well. It is a pasteurization technique being studied at Ohio State University. The need is to be able to monitor, display, and record to hard drive storage, voltage and current waveforms. They need to be able to draw information about the pulse duration, peak voltage, etc. from the recorded waveforms. Waveforms [...]
Lithography Optics Position Focus
Lithography Optics Position Focus Semiconductor Lithography Optics Position Focus Positioning Description One specific area where capacitance systems excel is high resolution focusing of complex lens systems such as those found in atomic force microscopes, vision inspection machines and photolithography tools. In a multi-million dollar photolithography tool, high accuracy, nanometer resolution and maximum thermal stability are absolutely critical to maintain proper focus and obtain integrated circuit line widths as small as 45 nanometers. Additionally, most systems demand low power consumption and maximum heat dissipation to eliminate any adverse affects from temperature [...]
Camera Shield Measurement
Camera Shield Measurement Consumer Electronics Camera shield measurement Surface Equipment Setup Equipment Used DTS-25-04 laser head Rotary Stage PC with Digital Microtrak Basic Support software Setup: Power is automatic mode. Filter is 100Hz Sample rate is 1000 samples sec The head was operated in diffuse mode (not specular/tilted) Validation of Setup The setup should be validated by performing a total runout scan on the rotary stage with no target present. The stage should be cleaned with Isopropyl alcohol and allowed to dry prior to the scan. This reduces any dust [...]
Phase Conjugate Sonar
Phase Conjugate Sonar Customer Case Dissipationless physical systems, such as simple planetary motion or a swinging pendulum, exhibit time-reversal invariance. This means that if time were reversed the way a film projector can be, then the resulting motion would be allowed by the equations governing the system. It follows that if all velocities in a dissipationless system are suddenly reversed, the system will follow a time-reversed trajectory. Dissipationless or adiabatic wave propagation is time-reversal invariant. Phase Conjugate Optics involves the deliberate reversal of complex light paths. A customer is doing Phase Conjugate Sonar using sound instead of light. The [...]
Tire Tread Measurement with 2D Laser
Tire Tread Measurement with 2D Laser Automotive Tire Tread Measurement with 2D Laser Depth Why Accurate Tire Tread Measurement Matters To maximize safety and tire longevity, modern tire manufacturers are adopting 100% tire inspection systems that include tread depth measurement, defect detection, and pattern recognition. Inadequate tire tread depth can lead to reduced traction, poor braking, and potential tire failure. Surface anomalies like blistering, bubbles, or belt overlap may cause runout, road noise, or even catastrophic failure. With consumer expectations rising and regulatory standards tightening, tire OEMs and testing labs need precise, [...]
