Hyperspectral Imaging 101 Feb 2020 1080p

Hyperspectral Imaging 101, an introductory presentation by Dr. Will Rock, Headwall Senior Applications Engineer. He is speaking slowly and deliberately for the benefit of viewers whose native language is not (US) English.

i need to know more about the light source! what type and spectrum. using filter or direct lighting from source. kind of source?

[@headwall-photonics]

Dear Tejeshw, for most hyperspectral imaging applications we recommend using a broadband light source, ideally with wide wavelength coverage and even spectral response across the spectrum. Typically that would be a quartz tungsten halogen source which is built into our illumination systems. The light often is directed into an intense but small area where the sensor is directed in order to be as efficient as possible. If you'd like to discuss your particular needs, please send us your email address to [e-mail] and we can correspond directly.

Excellent and to the point presentation. Thank you! I just have one question: How do you choose your polling frequency of the sensor (or other method) to create the pixels in the movement direction? Because these "temporal" pixels have to match the dimensions of the spacial pixels (the line) right? And this will be different depending on movement speed, fov and distance to the object.

Hi Thorwald, I apologize for the later response. You can choose the frame-rate and the exposure time of the sensor. In the case of a scanning kit or a compatible drone, you can set the speed. We do have a handy online FOV Calculator on our website that is also incorporated into our software: www.headwallphotonics.com/fov-calculator. Does this help? Sincerely, Headwall Marketing.
