Lidar testing and alignment, Imagine Optic is your sidekick

Lidar testing and alignment, Imagine Optic is your sidekick

May 21, 2025 | Misc, Optical Metrology

Lidar testing and alignment. Is superman just an early LIDAR adopter? and simply masters all its features to perfection? Superman’s arrival on earth corresponds to the invention of the laser and LIDAR (acronym for Light Detection and Ranging) technology. Are the...
Who the hell put his finger on my optics? Phase retrieval wavefront sensor

Who the hell put his finger on my optics? Phase retrieval wavefront sensor

Feb 12, 2025 | Misc, Optical Metrology

Phase retrieval wavefront sensor LIFT map reconstructed: Right. Residual wavefront error map acquired with standard Shack-Hartmann: Left.  I had the pleasure to participate to the mecca of optics, Photonics West 2025 held at San Francisco, proudly exposing some of our...
Shack Hartmann wavefront sensors: and yet they are achromatic!

Shack Hartmann wavefront sensors: and yet they are achromatic!

Jun 18, 2024 | Misc, Optical Metrology

Flat earthers claim that our planet is flat, despite any physical evidence and simple observation. Should we mock those who deny the obvious? Instead, let’s take the time to explain, and justify, on the basis of physical principles. We have known for a long...
Laser beam diagnostics: a new approach to ISO 11146 standard

Laser beam diagnostics: a new approach to ISO 11146 standard

Mar 4, 2024 | Laser, Misc, Optical Metrology

Laser beam diagnostics:What if Star Wars had deployed the ISO 11146 standard for laser beam diagnostics? We can’t rewrite history, but we can still delve into M2 measurement for your laser. (Image courtesy of Lucasfilm)   How is laser beam quality measured?...
Shack-Hartmann wavefront sensor, constant improvement of the technology through innovation

Shack-Hartmann wavefront sensor, constant improvement of the technology through innovation

Dec 18, 2023 | Misc, Optical Metrology

 Shack-Hartmann wavefront sensor . If Charles Darwin wasn’t thinking of the Shack-Hartmann wavefront sensor when he wrote his theory of evolution in 1838, it’s only because they hadn’t yet been invented. Since then, wavefront analysis technique has...
Flatness measurement, when surface flatness gets critical…

Flatness measurement, when surface flatness gets critical…

Oct 30, 2023 | Misc, Optical Metrology

Flatness measurement. Sometimes surface flatness really matters… either you are trying to break speed record at Bonneville salt flats like Dave Spangler or producing flat substrates and mirrors for high demanding applications such as Mersen. Boostec® Silicon...
