The handheld scanner incorporates a miniature near infrared spectrometer. The internal light source focuses a beam of light through the front window into the food. Light reflected from the sample is then collected through the same window. This light is then dispersed onto a micro-mirror device, and measured by an optimized detection system. This produces a digital electronic signal, known as a spectrum, that is characteristic of the food.
The Future TellSpec Scanner
TellSpec is currently integrating the Texas Instruments’ DLP technology into the TellSpec food scanner. The DLP technology allows our system to have a higher performance due to a higher signal to noise ratio and more accurate spectrum acquisition, as well as more flexibility in programmability for our chemometric algorithms.
Furthermore, the DLP technology does not require a laser which has many advantages for the consumer in terms of safety. By integrating DLP technology into our scanners, we will be able to give consumers better accuracy in detecting their food’s ingredients.
We also believe that TI ‘s DLP technology applied to spectroscopy will bring amazing new opportunities for the exploding Sensor Industry with all sorts of applications at a reasonable price point.
