نقد و بررسی اجمالی
VL53L1X
نسل جدید ماژول فاصله یاب لیزری براساس اصل ToF (زمان پرواز) است که در
کوچکترین پکیج حال حاضر موجود در بازار قرار گرفته است و فاصله را به درستی و با
دقت اندازه می گیرد. این ماژول قادر به اندازه گیری فاصله تا چهار متر است و با
قرار دادن یک معیار جدید در سطوح عملکرد فاصله سنجی، امکان استفاده از آن را در
کاربردهای بسیاری می دهد. انتشاردهنده 940 نانومتری VL53L1X
کاملا در برابر دید چشم انسان نامرئی است و پس از جفت شدن با فیلترهای مادون قرمز
فیزیکی داخلی قادر به اندازه گیری محدوده وسیع تری بوده و همچنین ایمنی بیشتری
نسبت به نور محیطی دارد.
Introduction
The VL53L1X is an advanced time-of-flight (ToF) laser ranging sensor that is a
miniature ToF sensor with an accurate measurement range of up to 4 m and a fast
measurement frequency of up to 50 Hz. It is available in a miniature reflowable
package with integrated SPAD receive array, 940 The nm stealth Class1 laser
emitter, physical infrared filters and optics provide optimum ranging
performance in a variety of ambient lighting conditions and offer a variety of hood
window options. Unlike traditional infrared sensors, the VL53L1X uses STToF
technology to measure absolute distances regardless of target color and
reflectivity. It is also possible to program the size of the ROI on the
receiving array, thereby allowing the sensor FoV to be reduced.
