New type-I linear optics based on holographic THz wave-plate replaces the old type based on cylindrical PTFE lens
In the past we have already dedicated a few articles to the topic our recent advances in developing a new type of optical components - holographic THz wave-plates. All our customers and web-site visitors keen on THz theme are welcome to get familiar with them posted on our web-site
Holographic technology is fairly simple, flexible, and cost-effective and its components allow creating a predefined beam profile required for a specific image plane (by means of using 3D printing ). Such technology opens up fundamentally new possibilities for shaping terahertz wave beams and is considered an important step forward in developing our THz optics for our TeraFAST- high speed linear THz scanner systems, both at 100GHz and 300GHz.
As a result Terasense R&D lab developed and presented a new type-I linear optics based on holographic THz wave-plate designed to be applied with our linear high speed TeraFAST- scanner at 100GHz. It is meant to replace (or substitute) the previous type-I linear optics based on cylindrical PTFE lens.
As compared to the previous type-I based on cylindrical PTFE lens, the new new type-I optics based on holographic THz wave plate has certain advantages as outlined below.
-(1)- In terms of THz intensity distribution, the new type-I optics based on holographic THz waveplate according to our experts can boast a more evenly intensity distribution pattern.
- (2) – In terms of Power-per-pixel and the incident power that reaches sensor array, the new type-I optics based on holographic THz wave is also a bit ahead of the previous type-I design based on cylindrical PTFE lens. A picture is worth a thousand words and you are welcome to see it for yourself at the comparative chart below.
