Color measuring tasks are performed in different ways. Tristimulus sensors are compact and optimized for large numbers and fast measurement tasks. Using an RGB filter, they are ideal for color detection. True color sensors with XYZ filter are suitable for absolute color measurement based in the Cie 1931 standard for human eye perception. Both sensors work according to the colormetric principle.
Their results depend on the light source and are subject in relation to the effects of metamerism. Although spectrometers are very precise and independent of light, they are also expensive and usually very complex.
They are slow due to their system and not suited for fast processes. A solution that combines the advantages of both technologies is more suitable – small like a sensor, robust and inexpensive, with the results of a spectrometer (highly precise and free of metamerism). Metamerism is the name of an effect in optics which creates the same color impression in people when objects with different spectral distributions look alike under the same light source.
The multi-spectral color sensor MMCs 6 takes this approach for specific applications in absolute color and spectral measurement.
The sensor is based on 6+1 spectral/selective detectors. It enables fast, precise measurement of the spectral power density interpolated via 6+1 channels. The detector supplies the measurement values, which are converted in the downstream amplifier and microcontroller directly in a color spot xyY/l a*b*/l u’v’ or optionally can be used as the starting point for spectral processing, depending on the application.
Yes, JENCOLOR is a Trademark of MAZeT for all our Sensors and Systems base on that technology for Color Measurement and/or Spectral Analyze. I'm Frank Krumbein and Product Manager for JENCOLOR Sensors ad Systems and/or resposible for key customers. I'll try to contact you - thanks.
As a technology company that develops sensors for Medical apps, we are definitely interested in developing a product that utilizes this technology.
Please contact us if you are Frank Krumbein, Mazet.
We like also this comment, you are right. It's always the same problem. I only used this application for skin measurement because in history often spectrometer were used for this and actally we make such designs. So our sensors help in this or other applications to make a system smaller, faster and cheaper in case of the sensor fulfill the customer requirements.
You are right and I'm honest, I like your comment.
In the moment we offer this technology preferably for customized projects with MAZeT. So please contact us to start the activities and implement the sensor into your new device.
The costs and prices for these sensors are highly dependent on the number of units. But they are in the lower 2-digit range(of dollars and / or EURO). Thus, the prices for these spectral sensors are between the typical low-cost sensor (RGB) and an OEM spectrometer.
A calibration for such sensors is possible but also depends on the application and/or light source, target and specified accuracy. We support this process of calibration by simulation and optimization. Please contact our sales team or me for more details.
I like the idea of a plug-off module for iPhone and we will welcome each company which wants to do it with us.
For years, multi-spectral imagery has been used in agriculture, forestry, water analysis and mining to name a few. If you consider human biology as merely an extension of plant biology then it makes you wonder why this application wasn't thought of years ago. The skin reflects, refracts & absorbs light frequencies using the same principles as plants, water & earth. I'd say it's a no-brainer.
Affordable spectral analysis has many applications; what price point will this technology support? How will the unit be calibrated to maintain accuracy through the life cycle? A clever attachment for an iPhone could go far...
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
