Digital Light Processors (DLP) make use of millions of micromirrors to produce vibrant, high-resolution images on a screen. The tiny micromirrors are placed on a semiconductor chip, known as a Digital Micromirror Device (DMD). This technology can be found in several industries ranging from Head-up displays and Smart headlights in the automotive market, Smartphones and other display and projection applications to advanced light control in 3D printing.
Heads-Up Displays, Imaging Sensors
Digital light processing technology (DLP) employs a light source and millions of tiny mirrors to produce vibrant, high-resolution images for a wide variety of industries and applications. It is critical to maintain an optimum operating temperature during use to prevent degradation of the digital light processor device. Active cooling solutions utilizing thermoelectric coolers can provide DLP thermal management in a wide range of applications.
Machine Vision is a revolutionary technology that enables analysis of a tremendous amount of data. It can be found in inspection systems where cameras capture and interpret images of a specific process or activity.
Machine vision is the replacement of human examination, assessment and decision-making with video hardware and software systems. The technology is often used for vision inspection, quality control, robotics, wire bonding and down-hole applications where machine vision systems obtain data from analyzing images of a specific process or activity.
For nearly 50 years CCD (charge-coupled device) sensors and CMOS (complementary metal-oxide semiconductor) sensors have competed on cost and performance in a wide range of digital imaging applications. Peltier coolers (thermoelectric coolers) have cooled both technologies when the requirement demanded high-resolution images. Design engineers opted to use CCD’s for astrophotography, super-resolution microscopy, x-ray crystallography, and spectrophotometric assays. On the other hand, CMOS sensors made inexpensive digital photography a reality.
Improvements in CMOS Sensor technology have resulted in increased readout speed and better image quality. Breakthrough technology has also increased image contrasts which paves the way for the next generation of digital inspection systems. The ability to rapidly provide high quality images makes CMOS Sensors useful in machine vision & learning applications as well as object detection & recognition.
The DA-014-12-02 is a Direct-to-Air Thermoelectric Assembly (TEA) that uses impingement flow to transfer heat. It offers dependable, compact performance by cooling objects via conduction. Heat is absorbed through a cold plate and dissipated thru a high density heat exchanger equipped with an air ducted shroud and brand name fan. It has a maximum Qc of 12 Watts when ΔT = 0 and a maximum ΔT of 50 °C at Qc = 0.
