They are used in Indirect ToF cameras to measure the phase delay of incident light signals modulated at 10s of MHz, reaching cm and even sub-cm precision. The principle was demonstrated in the late '90s and several commercial cameras based on this principle are currently available.<br />This reference explains the basic principle:<br />R. Lange, P. Seitz, "Solid-state time-of-flight range camera," IEEE J. Quantum Electronics, vol.37, no.3, pp.390,397, Mar 2001<br />You can find a list of commercial ToF cameras in the wikipedia page:<br />http://en.wikipedia.org/wiki/Time-of-flight_camera<br /><br />Lucio PancheriAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-86027648545233383372014-11-28T12:26:39.601+02:002014-11-28T12:26:39.601+02:00WTF?WTF?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-5199696232993037312014-11-28T11:51:03.338+02:002014-11-28T11:51:03.338+02:00One of the things I love about ASIC design is the ...One of the things I love about ASIC design is the sleek slender aesthetic.

Wonder if the decvice sees the light of day this time round. QVGA, 130kLux, 100m range, mm resolution sounds quite challenging to me. I wonder if such announcement serves the credibility of TOF technology.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-20778651836021411112014-11-28T08:12:45.518+02:002014-11-28T08:12:45.518+02:00Interesting.

Do you pulse your light source and open the shutter for 1ns? It seems like it will be challenging. I guess you can do tof by using multiple frames offset clocking by 1ns for subsequent frames to interpret where the signal is bouncing off of. Still this seems challenging. Does anyone know how these work?Anonymousnoreply@blogger.com
