Memahami Fotometri<\/h2>\n

Common photometric applications include testing the brightness of display<\/a> and uniformity of projection systems<\/a>. Luminous flux, luminous intensity, illuminance and luminance are the 4 basic concepts of photometry.<\/p>\n

Fotometri adalah ilmu tentang pengukuran cahaya tampak seperti yang dirasakan oleh mata kita. Aplikasi fotometrik yang umum mencakup pengujian kecerahan tampilan<\/a> dan keseragaman sistem proyeksi<\/a>. Luminous flux, luminous intensity, illuminance , dan luminance adalah 4 konsep dasar fotometri.<\/p>\n

Luminous flux, dinyatakan dalam satuan lumen (lm), adalah ukuran jumlah total cahaya yang dipancarkan oleh sumber cahaya seperti bola lampu. Untuk luminous intensity, dinyatakan dalam candela (cd) di mana 1 cd = 1 lm per steradian, digunakan untuk mengukur jumlah cahaya yang dipancarkan oleh sumber cahaya dalam arah tertentu. Pengukuran ini berguna saat membandingkan peralatan seperti lampu sorot atau lampu depan otomotif<\/a> yang menghasilkan sinar cahaya terfokus.<\/p>\n

illuminance, dinyatakan dalam lux (lumen per meter persegi), mengukur jumlah cahaya yang jatuh ke suatu permukaan. Misalnya, ini dapat digunakan untuk menentukan apakah ada cukup cahaya yang menyinari meja operasi<\/a> agar ahli bedah dapat melakukan prosedur pembedahan. Luminance mengukur jumlah cahaya yang dipantulkan dari suatu permukaan atau dipancarkan dari sumber cahaya seperti tampilan layar. Satuan SI untuk pencahayaan adalah candela per meter persegi dan nit adalah istilah non SI lainnya yang digunakan dimana 1 nit = 1 cd\/m 2 . Pengukuran ini biasa digunakan dalam evaluasi tampilan kokpit dan panel instrumen<\/a>, serta penerangan jalan<\/a>.<\/p>\n

Keterkaitan antara berbagai pengukuran tersebut dapat dilihat di bawah ini.<\/p>\n
